SHOCKING BAD SERVICE

I had a 2 year cellphone contract with vodacom that was meant to end last year, awhen the contract ended i realized vodacom was still deducting funds from my account, i then called the them to request stop the debit orders and ensure the contract was canceled on their side, the consultant i spoke to tried to convince me to rather upgrade instead of canceling and i still insisted the Contract should remain cancelled. Then consultants then confirmed than the contract is cancelked and no finds will be deducted moving forward, the following month after the cancellation i received a statement from vodacom indicating there is a balance of about R230 which was the monthly payment, i got concerned as i was under the impression that the contract was cancelled as discussed , i called and requested to speak to one of the managers and they explained that they will lodge a feedback for internal investigation and disciplinary for the consultant who should have cancelled the contract. The balance on the statement kept increasing until they finally sent me a statement indicating that i do not owe at all with a 0 balance. After a while i started getting calls from the debt collecting ageny demanding that i settle the balance, i sent them an email explaining that the contract was already cancelled. I requested that they communicate with vodacom to get all the correct details. NOW I CANNOT EVEN GET MY BOND APPLICATION APPROVED SIMPLY BECAUSE I CHOSE TO DO BUSINESS WITH VODACOM AND NOW M BEING TREATED DO UNFAIRLY AND MY CREDIT SCORE IS A MESS ALL BECAUSE OF YOU PEOPLE. PLEASE GET THIS SORTED ASAP
