Very Poor Service

Please sort your *****ed partners out: we went to make payment for 1 DSTV explorer, we were assured evrything is fine and we gto home it was not working. We called you call centre, got siconnected and had to call again only to be told that we have 2 decoders and you are still awaiting payment. The gentleman I spoke to (who was very helpful) advised that the system shows that we have too decoders and therefore, the payment that was made is short. We now have to call tomorrow, at our own expense, to have the second decoder cancelled. Apparently, the second decoder was activated 'as per customer request", please tell me why would we request o have a decoder that does not exist activated.
