Horrible Service

I booked my vehicle in for a diagnostics test on Tuesday the 27th. After a few days of no communication and struggling to get through to the branch and being told by the Lady (Roxanne) multiple times that she would call me back, but obviously that did not happen, I decided to go to the branch on Friday the 1st of March to find out what is going on with my car. I was then told that the timing chain needs to be replaced. The part that frustrated me was the fact that know one told me anything and they didn't want to give me my car back to take to a different branch because the car is unsafe to drive, in their words I then spoke to the manager Mumtaz Ebrahim. The very first thing that this man tells me is we don't have any loan vehicles, mind you, I haven't voiced my concerns yet or even explained why I am in his office . He then told me that a claim has to be put through to replace a part that was replaced at different different branch a year prior. My question was, If I didn't come to the branch on that day, was this claim even going to be put through? Why do I have to come to the branch in order for any work to be done? How long has my car just been standing? He couldn't answer any of these questions. He game me his number and told me he will be in contact with me. Here I am now. Tried calling the branch again. Was told by the same lady (Roxanne) that she is going to call me back but nothing. The manager also declined my calls. It's been a week since my vehicle was booked in. I still haven't received any calls or messages, no update whatsoever. I don't even know if the claim for the part was put through. This is ridiculous!! Why should I struggle like this? Why should I struggle to get staff to do the work that they get paid to do? It's not right that they aren't doing this to people and there are no repercussions to their actions.
