Short version of my huge annoyance:
I returned a laptop for repair on April 16 because the camera failed shortly after I bought it. When I handed over the device, I presented the warranty certificate to the customer service. After more than a week, migros.service sent me a text message asking me to submit proof of purchase. I sent both the warranty certificate and the purchase receipt again by e-mail and pointed out that I had already presented the warranty certificate and that I urgently needed the laptop again on May 5 as it was my work device. However, I never received a reply to my messages to migros.service@mfmag.ch.
On May 5, I received the same text message again asking me to provide proof of purchase so that the device could be repaired under warranty. A personal intervention on site at the customer service department at Limmatplatz yielded nothing, nor did further messages to the same e-mail address with the request to return the device immediately without repair.
Today is May 7, I urgently need my laptop back for lessons after the school vacations, I have no idea where my device is, whether it will be repaired and whether I will ever see it again. Now I urgently need to buy a new device as I can't teach without my electronic device. I actually assumed that the time off from teaching from April 6 to May 5 would be enough to get it repaired.
It's simply unbelievable how Migros treats customers, lets them go nowhere and simply ignores their concerns. I was a loyal Migros customer for a very long time, but I'm certainly no longer one. I assume that this message, like my many others, will not be read or taken seriously, this experience is one big disappointment.
