Harassment for an account I do not owe / never had

I keep on getting e-mails, phone calls and sms's to pay R14196.59 on a credit card @ Absa. I never had a credit card with Absa. I have been requesting the account number to sort it out with the bank, but they cant give it to me - neither can they give me any prove that the money was spent by ME. Received ANOTHER e-mail today, phone call day before yesterday, sms yesterday that reads: 4 days left! Still interested in settling your ABSA account? Settle 60% of R14196.59 this Friday. Pay via PAY @ using reference number at any Pick n Pay / Shoprite / Checkers. As I'm typing this complaint, received 2 missed calls from them ***)!!<br> Ref nr. is Acc AB010952<br> Woman that keep on sending e-mails with attachment (that do not open!) is Patricia Walsh<br> I've checked with Absa - they have no records of me owing them money and nothing on ITC either<br> Please stop this - unless you can send met the documents and prove of this imaginary account!
