Sick and tired of being harassed

I'm constantly getting calls for M Hoffman from Standard Bank . Its been months now and I constantly tell the consultants to remove my telephone from the person's profile. If its not for credit cards that's in arrears than its for a home loan that I don't have with the bank. They than apologize and assure me that it will be done, but a week later i get the same telephone call . It feels that I'm being harassed by the Standard Bank Consultants.
