harassment by Wesbank

I have paid up my car over 7 moths ago in Full and subsequently Wesbank still send there agents to repossess my car. I have received the car's original documents from Wesbank and the car is now registered on my name but still there agents harass me. What angers me most is that they tell my Neighbours that i owe the car and that they are there to repossess it, this is ********* and puts me in a bad light. They even go to the local shops in my area and tell the people that i owe, which is not true.
