Teljoy's Bad Service

I have previously been a customer and am currently a customer and I have never experienced such bad service from Teljoy before. My microwave stopped working on 3 Jan 2023. I understand that it was before most businesses were actually open for the year, but it took them until the 11/12th Jan and numerous phone calls to collect said microwave. Today is the 14th Feb 2023 and I still do not have a microwave to use, or even been given a replacement. I have made weekly phone calls to follow up. I have sent numerous emails to a certain individual, who always either ignores my emails or gives me the brush-off by saying that she contacted Defy and is waiting for a response from them. I have on numerous occasions tried to get hold of a manager only to be told that she's either out of the office or in a meeting and none of my messages get a return phone call. I was told yesterday that my microwave has been fixed but that they can't give me a date as to when it will be delivered to me. On numerous occasions I have insisted that they have until the end of the week to give me back my microwave or give me a replacement. I live in hope that I will finally be given back my microwave BEFORE the end of this week.
