They can do nothing right!

ERIC BAD!!! I had a contract for my daughter. which I took out 3 and a half years ago. She emigrated to the UK about 3 years ago, so the phone has not been used on the Vodacom network during the vast majority of the contract, HOWEVER, not a single payment has been avoided. I called their *** number to cancel in August, September and more to cancel ALL the contract bits and pieces and was told this was done (multiple times). Subsequently, I have received billing showing a zero-balance owing BUT, they still debit my bank account which I reverse for obvious reasons, NOW I get a message from Clearscore dropping my creditworthiness because of Vodacom. Does anyone know how to contact these oxygen *******? I've tried mail, phone and visiting their shops, nothing works. Anyone reding this who needs a phone, DO NOT USE VODACOM, they are a public enemy. ******* company, too big to give a damn.
