Paying for service we do not receive

Our company has a 24 month ADSL contract with Telkom for 20GB of data. Yet by the 4th of every month we get a notification from Telkom to inform us that we have reached our 20GB limit and our account has been capped. <br> <br> When we call the accounts department we are told that we have not yet reached our cap. Today we were at 9GB of the 20GB that we are allowed. Last month the same issue, I purchased top-ups in order to get work done.<br> <br> I have been sent from department to department and no-one can tell me why we have data available but our account has been capped. The department who apparently should investigate and give feedback, has been ignoring my emails since 2 July.<br> <br> We are paying for a service that we are not receiving. Our business is loosing valuable time and money because we can not work sufficiently.<br> <br> Think twice before using Telkom as your ISP.
