Order never placed

Last week thursday a gentlemen phoned my husband to tell him about a new deal Telkom is launching, after a long discussion we did not take the deal but decided on a uncapped deal with a faster line... We were told that it would take 48hours to be active, we even got a ref nr stating that our order is being processed.. After 48hours we used the internet not that sparingly under the impression we had uncapped. We received a email on monday night which said we have almost reached our data limit, we contacted telkom this morning and the order was never processed almost a week later. Now our existing data is almost up and my husband needs the internet to work.. After this experience we will never buy anything from the call centre and if this is not fixed Soon we will be moving to a much beter service provider
