Defy Service ****py

I have a Defy fridge that started acting up in December 2019. It had and still has a warning light and on the 3rd of January 2020, I decided to report this with the Defy service department. The first phone call went smooth and I was told that the turnaround time was 2-3 working days and I should expect technicians at my house in the following week. I absolutely thought that was an amazing experience until the "following week" went by and no communication from the service centre or the "techie". The following week which is now the second, came and towards the end of it, we had a community strike in my area and I understood that the techie would not be able to get access into my house. The third and fourth weeks also came and went by and without communication from the service provider! On the fifth week, I get a phone call from someone that happens to be the techie and this is at 7pm. I am preparing to sleep and the technician tells me that he came to repair the fridge!!! Really Defy????? What nonsense is that??? I turned your technician away because it was NIGHT time and there was no arrangement made between myself and these people for night repairs. Now, my call/job card has been canceled because I didn't let the techie into my property AT NIGHT!!!! Is this the kind of service you serve to customers? To worsen the situation, today I called the branch that is supposed to help me and one arrogant girl tells me that was in fact good service and I should be thankful(absolute BS) that they tried to help me. Please investigate my reference number ***. Your call centre in Midrand is useless and from my calls with them, I could pick up that there's no sense of urgency!
