Poor sevice

I received my invoice for my telkom mobile device. I paid the bill via eft. I always pay it before the due date instead letting Telkom debit me. Telkom mobile suspended my line. I have no idea why. When I called them on 081180 they confirmed that the money I paid is reflecting on my account and I don't owe any money. The agent advised she mail another department to lift the suspension. I was told it will take between 5 to 24hrs to resolve. This is unacceptable. Telkom sorr my problem out ASAP or I shall lodge s formal complaint and probably end up going to the ombudsman. Awaiting your response
