Mtn very poor customer service.

I took out a new contract with mtn NOTE 9 pre order promotion at the Mall of the North store in Polokwane. When I went to collect the phone, no one knew about the promotion. Eventually they found out about the promotion and how to get the tripod, wireless charger, docking cable and 24 inch samsung curved monitor. I eventually received the wireless charger, tripod and cable in the post. After waiting for more than a month for the Samsung's 24 inch curve monitor, i went back to the store to find out what was happening. They now say that the promotion never existed. They then phoned the Samsung representative, who told them that I was suppose to order it online. They still have not sorted my problem.
