MTN and Rewards - I want my money back

I got a contract for the R249 uncapped deal. Purchased two of the packages and paid for a month in advance. A courier company driver from DSV came to deliver the parcels. They had a faulty biometrics machine that they couldn't sort out. He ended up leaving with the parcels. Two days later I called because I had not heard anything either from MTN or DSV. They rescheduled delivery, however there was some sort of problem on their side. When they rescheduled, the driver didn't have the correct address, he went to the wrong one. He couldn't deliver because he had a different address to mine and therefore had to reschedule because DSV needed to correct the address. I immediately called DSV, the agent told me that the parcels had actually not left the warehouse and they will reschedule.

I have made a request to be refunded my money because I have been sent from pillar to post and taken for granted. I cannot spend another cent on a service provider that has very little regard for the customer.

Please start the process of refunding me.
