Worst and bad service ever

This is the second time i had a unit with a problem on and every time it's the same story with Teljoy previous unit as well no feedback, no happiness takes forever to do repairs or replacement. And every time i phone it's the same nonsenses we will escalate the matter and get back to you tomorrow and nothing. Very very disappointed in the after sale service you are on time with the debit orders but to fix or replace a unit never ending issues. I reported the unit on the 3rd of December 2021 and we are on the 4th of January 2022 and still I have no idea of what is happening or how long this is going to take was the whole of Dec without a Microwave but I still have to pay for the month ??????????????
