AUTO BARN, Mt. Edgecombe Poor service and no customer service.

Bought a crank sensor in September 2018 for my car, was told that if we did not need the part anymore we would have to return it but do a claim process, however we are Gauteng based and had to return back home leaving the car in a relatives hands and the mechanic that was to fix the car, so the mechanic that fixed the car said the part is not working and he tested it on another car and altogether was not even needed as the car had a different problem, so the process began with contacting the staff at Autobarn and was told to fill in a claim form and get report form mechanic, however they would never return call, i had to constantly contact them up until now even they will never respond to any emails, but eventually got the forms filled it in and was told by the mechanic he had contacted them and given them feed back as he usually deals with them. I had to contact them again to confirm all this and they seemed happy to continue but they also seem to have a dont care attitude. no sort or urgency or pride in what they do. As a customer would like some sort of feed back so when i do call them they say 4-6 weeks waiting so we waited also doing usual in between follow ups. Eventually my husband got involved and the guy dealing with it was never available but and no one ever called back returning his call. When i called afterwards he told me they also still waiting for feed back from head office. My Father in law made a personal trip to Durban and we asked if he could find out the situation and whats going on. He was then told the claim was rejected due to insufficient information. Which i feel is bull as they deal with the mechanic all the time as was it was told by both the Mechanic and Autobarn and accepted his verbal information, hence me not pursing a written diagnostic. Why would they go out of protocol and now reject the claim they where happy to proceed and now i must suffer the consequences for their negligence and poor workmen ship I must now suffer. Now they dont want to give me back my money and they still have the part. Service was pathetic, no sort of pride in there work and worst no care attitude. Its a lot of money for me to loose with no proper feed back, and there lack of attention or following proper procedure has now cost me, they dont even bother to make any attempt. Its frustrating having to constantly contact them and follow up and worst not getting answer, what are they there for.
