Pathetic service MERCEDES BENZ SOUTH AFRICA HEAD OFFICE

I have recently purchased a mercedes benz ml350 bluetech amg from Mercedes benz repo department via a public auction. The guys threw 2litres of petrol from the repo department then realised tht its a diesel vehicle. Car gets towed into mercedes dealer in Durban and gets a quotation of a R155000. The vehicle then gets towed to another merc dealer who drains out the petrol fitted a new diesel filter and throws in the correct fuel which is diesel but the original dealer it went to umghalanga mercedes benz which tried to ******* some1 puts a note on the system entire fueling system needs replacing and quotes 155000.thus mercedes suspending the motor plan.i called shiraz auto and seeked advice from the service advsior who contacted mercedes and asked the way fwd and told me a quality check needs to be done anf if any thing that is wrong on my vehicle i have to pay upfront and then mercedes will relook at reinstating my motor plan provided there isnt any issues and provided the vehicle passes the computer checks and processes etc.i purchased the vehcile on the 11th of september and filled diesel in durban and drove up to jhb as i made a booking with shiraz auto for the 13th of september. shiraz auto always gave me excellent service and even collected my vehicle from home the next morning and glady assisted me and advised me . I service all my mercs at shiraz auto the staff and service is always excellent and accomodating. The service advisor then gives me a bill 3days later off R32000.00 and says the service needs to be paid.brakes brake discs etc so thts why a hefty bill but your vehicle is according to Mercedes standards and everything is in order and they will submit my vehicle report to Mercedes south africa but there is no reason for them not to reinstate my motor plan .so i paid the R32000 and after 2days receive a call from shiraz auto stating mercedes has refused to reinstate my plan and i must call Mercedes south africa but they cant understand why as my vehicle is within the mercedes standards and there is no issues as to why. I spk to a gentleman david who gves me a ref number and then calls me back the ffg day i think and says sorry mercedes isnt prepared to assist me i must call the ombudsman.furiously i ask to spk to a manager and he says they do not take calls. After numerous attemps and people giving me names i then get referred to lance at mercedes who was extremely rude to me and mercedes sa calls are recorded and so is mines. He then tells me that if shiraz auto gives him a fuel line report as a 60point check doesnt serve the purpose of what the problem was and if tht report is fine he will reinstate it. Surely mercedes benz dont hve **** equipment and the technology they use is accurate. I then send my vehicle back to shiraz auto and they send a report to Mercedes benz south africa and still no feedback.i made numerous calls over 20 to 30 to get into touch with lance but i was told he doenst take calls he doesnt speak to clients and they will get him to call me..i have ref numbers and recordings as well as there calls are recorded and left numerous msgs but non of the staff members can put me through to a manager. What service is this.. i then leave msgs day after day but no luck to speak to a senior or manager.i honestly feel ********** paying a hefty bill by instructions of mbsa and then get shunned away and problem remains unsolved..pathetic service from Mercedes benz south africa. No morals or integrity by returning clients calls and no business ethics..i serviced 6 or 7 of my Mercedes benz in that week as well but after receiving service in this manner is disgusting..no other words to explain the service level of mercedes benz head office. Unfortunately i was told constantly at mbsa head office managers dont take calls.. so who the hell should i speak to if managers dont take calls. Till to date i was promised by lance i will get feedback and he will follow up unfortunately shiraz auto continuously strives to gve me excellent service by calling head office to escalate the matter. I would like to knw in writing as to why mercedes wouldn't return my calls and why wouldnt they reinstate my plan after there own machines,technology, equipment states tht my vehicle has no issues and rips me of a bill of R32000.
