More than 15 years ago Wesbank started pestering me with regard to a loan account

More than 15 years ago Wesbank started pestering me with regard to a loan account. I have on multiple occasions provide them with documents and paperwork informing them that I never had and I never will have an account with them. Now after a silence of 4 years a company called nimble started harassing me in respect of a Wesbank loan. First of all this is harassment from the very beginning and secondly, after so many years surely this claim expired or maybe I should just agree to what they want just to get a summons and start defending the matter just to waist my time and your money and then put in an harassment claim just for the fun of it. Wesbank!! You should really get better information on your clients or get with the program but STOP HARASSING INNOCENT PEOPLE. Just for your information, all my vehicles ever bought was financed by Standard bank
