Being send from pillar to post for a reconnection

My name is palesa rabele...I phoned multichoice for a reconnection of my decoder...They gave an amount about a week ago and I paid...when I phoned to let them know they said the payment hasn't shown yet...and then this morning they send me I owe R372 more...when I phone to query that I couldn't get an answer in fact I was only today after speaking to these agents more than 5 times that my decoder card has expired...like really...why couldn't someone say something earlier??? I really am not happy because phoning them costs me R30 or more...
