Disgusted

I had a contract with Vodacom for a period of 24 months. I cancelled the contract on time when the contract period was up. My bank account was debited monthly by Vodacom. Recently I received a credit report from Experian only to discover that Vodacom reported that I am in 6 months arrears for a payment for January 2024. The account was debited in January 2024. I called Vodacom..was referred to all the different departments but was not assisted. I have sent numerous emails but the issue still stands.... disgusting, doesn't even deserve a 1
