Disappointed 😥

I recently am experiencing alot of problems with vodacom. Recently I was wrongly charged for early cancelation fees for a contract and after months of waiting for it to be rectified I was credited that amount as a credit so my future debit orders would be deducted from that credit . It should at least of been four or five months that I should not have been debited but it only happened twice then u started being debited normally again. When I enquired the consultant couldn't seem to help me. Now I don't know anymore
