bad customer service..delayed feedback

Good morning ive been struggling with turbo direct for more than two weeks now on feedback of my turbo..ive been without a car for more than a month and a half because of their bad service..they have been telling me they waiting for feedback...or its either they busy compiling the feedback still..there is always an new excuse..ive been checking up on them..they hardly give me feedback...and my warranty insure africa is not helping at all...I need to call them and they always tell me they will call me back but never do....I need help to sort out this bad service and delay...I'm struggling without my car..need to take out more for transport because I don't have a car...kid needs to get onto a bus where as I use to drop him at school...its extra costs for me....warranty cant even give me a hired car,even tho my warranty has car hire...
