Incorrect email address and harassment

Once a month I receive an email stating I am under debt review. That's great but I DO NOT BANK with Capitec Bank. The email address that was given by the actual client is incorrect (first of all this should surely have been verified when opening an account) - Anyway I phoned numerous times for them to rectify this and rep**** to many emails to remove my email address - I still keep getting emails on a monthly basis - If you want your money from the person in debt please make contact with them via tel number and remove my details please.
