They don't want to discuss the problem on the phone. You have to send an email to migros.service@mgb.ch. But you don't get an answer. Instead, I receive an e-mail without any text but only an invoice for 276 francs. There has been no response to my second e-mail either! Here is an excerpt from my e-mail to migros.service@mgb.ch Dear Sir or Madam, Mrs. Clavadetscher Now I am really annoyed with your customer service.

First, you didn't call me back as promised, but instead asked me for a written statement (supposedly to "clarify the facts"). And when I responded to your request for an explanation, you didn't even consider it necessary to answer me, but simply sent me an invoice for CHF 267 without comment. Excuse me, but is that still possible? Is this your idea of customer service? I would like to ask you one last time to reply to my previous e-mail and explain the following to me: If it is so clear that "burn-in damage is not covered by the warranty and is subject to a charge", as you state in your e-mail, why was I not told this directly during my first call?
When I emphasized - several times - that it was burn-in damage? I now have the impression that a follow-up order - the purchase of a new TV - was to be generated here, in which the costs for the replacement device would then of course have been deducted, right? About the invoice: Excuse me? Fr. 218.- for bringing and collecting a replacement set? That's simply outrageous. Incidentally, Fust charges Fr. 85.- once for the journey, regardless of how often the technician/mechanic comes here. And... Fr. 49.- for plugging in a few cables is also more than borderline.
In any case, I am not prepared to settle your claim. And I will certainly never take out a warranty extension with Migros again... I am now giving you three working days, i.e. until 9 September 2020, to respond to my emails. I am now giving you three working days, i.e. until September 9, 2020, to reply to my emails and come to an amicable agreement before I hand this tiresome matter over to my legal protection and - if necessary - also draw the attention of Kassensturz to this problem. Yours sincerely P.S. As a reminder, my email of 03.09.2020 to migros.service@mgb.ch Dear Sir or Madam It is a pity that it is apparently no longer possible to clarify simple issues verbally, i.e. by telephone. Although I was promised a callback, it never happened. So: When I first called your customer service about this matter, I said clearly and repeatedly that it was a case of burn-in damage. And that it was getting worse and worse, even though we were running the repair program on the TV every day - sometimes several times a day. So you knew what the problem was right from the start. I said the same thing to the technicians who came to collect the TV from us. They said that it was probably not repairable, but that the TV would simply be replaced. And then - after your device analysis - you informed me in writing that burn-in damage was neither repairable nor covered by the guarantee. And that I should pay a contribution towards expenses of CHF 30 for the unrepaired return (plus -undefined - domicile expenses for field service orders). But quite honestly, I see no reason why I should pay even a single franc for this completely unsuccessful, unnecessary action.
You were fully aware of the problem (burn-in damage) from the very first time I contacted you, so your immediate response to my warranty inquiry should have been: "Burn-in damage is not covered by the warranty" and we could have saved ourselves all the subsequent expense!

And therefore: I kindly ask you to dispose of my old appliance and collect the replacement appliance from us as soon as possible, because we have already bought a new TV from a small dealer in the region, from whom we hope to receive a more competent and uncomplicated service... For the collection of the replacement appliance - at your expense! we offer you the following dates: Thu. Sept. 3, 2020 Fri. Sept. 4, 2020 Sat. Sept. 5, 2020 And every Friday thereafter, with a maximum three-hour window of advance notice on your part. AM VERY EXCITED. BUT FORM YOUR OWN OPINION. My opinion is that if I don't receive an answer by 09.09.20 I will switch on the Kassensturz. I have a new TV from Tele Locher AG, a small company. There you also have time on the phone to clarify something or buy a TV. I'd rather spend a little more money than a dozen telephones and mails where nothing else comes out. Oh yes, and who pays me for all the telephone charges and my time? And not to forget the storage for the TV that Migros gave me? Yes, I am extremely angry with Migros, I hope that I am the only one who has had such a bad experience, otherwise it is an indictment of a cooperative! Have you also had such experiences then have the courage to write it here.
