Pathetic service!

On 29 October 2020, my Tata Xenon broke down. We took the bakkie to Renault Princess crossing. Portia phoned us the next day to tell us what it would cost and that it would take at least 3 weeks(20 November) for the part to get there. We paid the amount she sent to us. 3 weeks later (11 December) when I phoned again, I spoke to Urache (sorry for spelling). He could not find anything on my vehicle and asked for my reg nr, which I gave. He did not even know the vehicle was booked in there. He phoned me back a few minutes later just to say there is no stock of the part. That after 3 weeks when it was supposed to be there. He said he would order it and it would take 3 weeks again. When I phoned again after 3 weeks, still no part, but they promise by the next Friday (18 December) it would be there. Friday I phoned again and still no part. This is really unacceptable. This is now 8 weeks this Thursday without anything being done. And they never phone back when you ask them to. Now 22 December I still have not heard a word from him. Really how much more time do they want. Please people don't take your vehicle there. Most pathetic service ever!
