telkom billing to much

<p>i took out a contract with telkom on the 29th of January, for around R200 a month, i got billed at the end of February for almost R900, i dont understand how they work. There is a big difference between 900 and 200, they dont even tell you this at the store. i tried calling them, but with telkom you have to wait for a long time. waste of time and money:(</p>
