Cancelling my line i just received.

I just received a new line from Telkom and went to the store only to update my new details and remove the data portion ONLY. Now Telkom calls me to let me know the people at the store cancelled my whole line! this is not what i requested and now i am sitting with no connection and even had to pay as they suspended my line without notification. Is this what i must get used to as a new client? What all must i do to re-apply and get my line back up again which is such an incontinence as this is not what was requested?
