Total Harassment very BAD

I am being Harassed on a daily basis with calls different numbers. They call from morning to night even on a Saturday evening asking to speak to some person who had taken a Wonga loan and has not paid. I have told them numerous times I am not the person they looking for and that they remove my cell number but it’s never happened. I requested to speak to their Manager but they say the Manager is not available. This is the link and amount R4165.34 have been SMS https://payat.io/qr/*** insisting that I pay. This is very bad service from a company I don’t even know. I am not happy and want my details removed. REMOVE My details
