Terrible

<p>I took a contract for data from yello data last year .The contract was for 1gig for R99 and it was explained that once you reach 1gig its done meaning it is capped. I was billed then with R490 something and i reversed this. I cannot get hold of my monthly usage as they wont provide this and its a problem to try get through majority of the time. They have stopped debiting my account but i keep getting the 1 gig data each month. I have called them to get this info and the help centre is terrible with service. I need to get the bill and my usage as i do not want a hefty bill. PLEASE HELP</p>
