Unhappy

I had a data contract with Vodacom and when the contract expired I notified them way ahead of time that I do not want to carry on with the contract and that it should be cancelled on expiry of the 2 years. Now I need to see on my credit report that I missed 2 payments for the last 2 months. To get hold of customer services is almost an impossible rask. This is exactly the reason why I never will deal with Vodacom again.
