Cell c contract not cancelled

I am writing this review on behalf of my husband. He had a Cellc cellphone contract which was paid in full and concluded at the end of November. His account was debited in December even though the contract had ended he queried this and was told that the contract had been cancelled his account was then debited for twice the amount again in January he went into a cellc store where a consultant confirmed that the contract had been cancelled - February his account was debited yet again when going to the store it was found that the cancellation had not been processed on the system and was told that he would have to pay an additional 2months! This is broad daylight *******! we also met another customer in store who had experienced the same thing.
