I was unlucky to deal with Totem twice recently (because I was told that they are the ONLY service provider for Liebherr fridge/freezer).
For the Liebherr fridge/freezer Totem technician came to see why (after renovation) our built in unit is slightly miss aligned. He told us that a long screw used to align rear foot is broken and he needs to order the WHOLE REAR FEET UNIT from Liebherr (it was son September 11th, 2019). Part was ordered and I was told that it will take about two weeks to get it. I called them three weeks later to see when service will be provided and was told that technician sent part back "by mistake", they will order part again and will come later. Yet again, few weeks later, I called them and had technician scheduled for last week. On a day when service supposed to be provided I got a call with question when I would like to have a service!? When i told than that is supposed to be on that day I was told that they have a "glitch in their system" and that they have to reschedule it for next week (November 5th, 2019). Day before scheduled repair technician called me and told me that he ordered a "wrong part" and that I have wait more and more.
I finally got a contact for different service provider, he told me over the phone that, most likely, screw is just detached and, if I pull fridge out, I can do it myself.
