ex rude MAHRINDA Newcastle manager goes to join GWM Newcastle

This review is not against GWM but a GWM management level member. I purchased a brand new Mahindra vehicle in 2019 at the Newcastle branch; at this time there was a Manager who has now moved on to GWM. On picking up the vehicle I found that the passenger would not open. My vehicle has been sitting for some weeks and had never had a check over for my collection. A radio was installed by Mahindra's supplier which never worked properly and was problematic. The door issue was because the supplier did not reconnect the door cables after installing the radio. This issue has carried on and on and I traced the 'manager' to GWM Newcastle because I had to have my radio reconnected to industry standards which obviously cost money. This sent the bill to this GWM Manager and he denies that is has anything to do with Mahindra and not covered by warranty (which I agree but they employed the services of the radio installer ... all their vehicles use the same installer). I would like GWM Head Office to rather encourage this manager to re-imburse me for this cost and all the backwards and forwards to Mahindra PMB to get this sorted. It puts Mahindra's name in a very bad light employing a so called manager that may give the same lack of service to GWM clients.
