Multichoice pathetic service

Multichoice has not been debiting the actual amount I signed up for. On Saturday they suspended my account claiming that I am in arrears where as they have a scheduled a debit order. I had to call to sort out the matter since during the day,I had to provide proof of payment and it was only sorted out in the evening. Today they suspended my account again claiming that I am owing about R689. So meaning that this will be a weekly drill and charging me ridiculous phone tariff as I call and fight for an hour everytime!!!! Its shocking honestly!!!
