Identity Theft

I have never had an account with RCS and I've never app**** for one. I received a call from their call center a day before asking me some question's about the acccount I have with them. She told me I opened an account it has opening balance of R40 000 and about +R8000 has been used. I mean how do people open accounts in the shop nowadays? Don't you need to produce ID, Payslips, Bank Statement, proof of res? Don't you confirm employment with their HR? Im very dissapointed with how this company operates. What makes me more angry is thry have my number now couldn't they use that number to confirm with me when the account was opened? I just forwarded RCS my affidavit and other documents they requested and hoping this matter will be sorted I honestly don't need this right now.
