BAD CUSTOMER SERVICE

We are a touring Company that purchased a New Sprinter in Jan 2015 and purchased a full Maintenance Plan with the vehicle. In July 2018 with only 58000 klm, the injectors needs to be replaced and I booked the vehicle in. Only to find out a few months later that my plan was a best basic plan and not a full maintenance plan and that I had to fork out R70 000 out of pocket. I refused to pay because I have a maintenance plan and am still busy fighting with Mercedez Benz. My Vehicle has been standing in Montague Gardens for 8 months now . Who is going to pay for our loss of income for all this time ???? The vehicle was standing there throughout the our peak season and we could not service our regular clients requesting this 22 seater and had to give away all the work that was booked for this vehicle. To think that Mercedez Benz could treat a client who has more that 12 Mercedez Benz vehicles in this manner ?????? They took so long to let us know what was happening. We sent Email after email and phone call after phone call. Really bad Custer Service. They schedule meetings then on the day while we are there already we find out that 1 of there members is not in work today. How Unprofessional for such a huge Company ???????? From A VERY UNHAPPY OVERLAND TOURS......
