*****lent details provided for contracts

I have now started receiving SMS's and emails for another persons contracts. I have now tried to contact Telkom to get this sorted but the person in the store was not able to help because I don't have the account open with my ID number and the call centres are saying that they have no way of finding out who is using my details. This is ***** and I want to find out what is being done about it. I refuse to wait until I am debited to be able to lay a complaint. I have tried to inform Telkom of this and they are not willing to help. How can I get this resolved?
