I have had it with the service from multichoice

I am absolutely appalled about the service I received at Multichoice. I requested them to change my debit order from 1st day of the month to the 25th. Two consecutive month they debited lat. This month they debited on the 3rd of the month and the debit order returned unpaid which is an inconvenience for me. I am tired of multichoice and their poor service and I am close to changing to a different option. When I call the call centre, I get an appalling service. I am annoyed off, they not taking good care of their customers, why should we continue with them
