Payment function on eTshwane website

We made a payment to the eTshwane website on our account. Almost two months later they have not allocated it to our account. You would think that a card payment to the website would be almost instant. They claim that there is a problem with the website not linking it to the account, but there is no error message on the website. The payment function is not disabled. Thus eventhough they are aware of the problem, they just don't do anything about it. I have phoned and sent emails numerous times, but to no avail. Only empty promises and no feedback or results. I have never had such bad service in my life! There is no excuse for incompetence...
