poor service from Magnis team

Poor service ,when you have a problem and you try to take the matter to the Dealer principal. He will not answer your calls and even respond to your message. It's now 3 days since I left a message and up to now and its not the first time. I don't know if its the way they treat to all the customers? I think UD South Africa is not doing it's work to see if the dealerships are operating according to UD standards. I hope Magnis group will also look into matter serious as it will also affects the company to go to greater heights. I have been a customer with magnis sinice 2007 so I see a lot of differences. instead of going up the dealership is going down in terms of standards.
