Very poor customer service

We requested that our service be cancelled due to poor service and undesirable service offering. They cancelled then reinstated without our request but cannot explain why. Approximately 2 months later and we are still awaiting our full refund. Further, I was referred to a Supervisor who made commitments to resolve the matter and confirm same but he has neither done so nor responded to my follow up queries. Shocking but unsurpising from Multichoice.
