multichoice needs help to work their own product

Mnet decoder was faulty swopped it for another in Benoni. Got home phoned *** so for this centre to load the new serial number. I was told an hour then 24 hours then some guy just left me hanging. He had no other lies to add. Well from 5 sept at 13h30 till 6 sept 18h53, i still have no mnet. Paid in full but just promises. No one answers emails so multichoice is one of the most unorganised companies and cannot provide a service. I am still off people, but pay, one must pay first. Multichoice hides behind their telephones and not one operator gives a reference number at all. I am not impressed and no one at multichoice can help. So now i am at a dead end. Sadly.
