Empty Promises for Refunds

We took out the R799 Explora Special in the beginning of Dec 2014. No one phoned me in the promised 3 days about delivery. I then send numerous emails requesting the date of delivery before I went on vacation which I did not had a reply on. We left for our December holiday on the 17th of Dec '14 and the courier company only phoned me on the 22nd of Dec '14 for the first time. I told them I was already on vacation and only coming back on the 1 st of Jan 15, they must deliver on the second. Which they did after I had to phone them and make sure they are going to deliver. When we received it on the 2nd of Jan 15 it was also installed on the same day. I phoned Multichoice on the 31/12/2014 to enquire about my account and told them they must reverse the extra instalment and also the prorata amount that was on my account for which I was billed for something I did not had at that specific time. I was given 3 reference numbers from the 31/12/2014 until first week in Jan'15 promising that they will refund me. I am still sending emails and it just seems to me no one want's to help me. But they are very quick to debit your account but to refund you is a ongoing slep...
