accounts department not doing their job

My wife and I were in Cape Town for the Argus on the weekend of the 6th of March. I hired a car for a few days which caused some issues with my Credit card as I had 6000.00 rand blocked fuel and insurance purposes. This cause a bit of delay in my payment of my account. I confirmed that i would pay my account on the friday the 11th to there automated collections department. I then paid the account early in the morning of the 11th as I said I would. Ysterday I got a message saying that my data for my internet package was finished. I called the customer services to ask them to load me some data but was told that sorry my account is locked. After the assistant checked the account as per my complaining that I had paid he said that the account was in fact up to date and was not sure why it was still locked. I asked him to please get somebody to sort it out and load me some data. I was told that sorry but only accounts could unlock it and that he would have to get them to contact me in the morning. After a bit of stressing I then aggreed but have yet to receive a call from them to sort this matter out.
