Absolutely Pathetic Service and robbery - MotorServ

I purchased a Mahindra Bolero on the 20/03/2019 from Mahindra East Rand, at the time of purchase I was sold an unlimited kilometer service plan by Mahindra East Rand from MotorServ. My vehicle had been serviced timeously since purchase. My vehicle is currently overdue for service however to date MotorServ is yet to authorize my service claim. I had emailed MotorServ my service claim on the 10/06/2020 when my vehicle was doing 48,430km and after 2 days of not receiving any feedback, I called MotorServ, I was informed by reception that she was unable to contact her boss but that she would pass my message to him. I sent a follow up email the same day - 12/06/2020 after I had still not received authorization nor any feedback. I called Mahindra East Rand on 15/06/2020 as I had still not received any feedback and had by this time been informed by MotorServ reception that only her boss and her worked at MotorServ and he was unreachable and there was absolutely nothing she could do to help me. I spoke to Cyndy at Mahindra whom advised me that all their customers were having the same issue and that this was escalated to Mahindra SA. After numerous emails and telephonic conversation still nothing had been done by neither Mahindra nor MotorServ, I contacted Warren - managing director at Mahindra East Rand on the 22/06/2020, Warren now informed me that i should book my vehicle in for service and pay for the service in cash, to which I replied that I have purchased an unlimited service plan and paid for this in cash after a back and forth with Warren I was told that i had purchased the service plan from MotorServ and not Mahindra and he was not willing to assist me any further, in my defense the motor plan was sold to me by Warren of Mahindra East Rand and now he sits back and tells me that it is not his problem if the company he vouched for is in financial problems. I will definitely not purchase any vehicles for Mahindra again nor would I advise anyone else do. Mahindra East Rand is quick to sell you a vehicle and add-ons but at no point do they take responsibility for their actions, Mahindra East Rand & MotorServ and the employees including the managing director do not know what customer service is and are absolutely pathetic in servicing their customers. I am taking legal action against Mahindra East Rand and MotorServ respectively.
