Harrassment Won't Stop

I am being harrassed by Izwe loans on a daily basis to take up a loan and if they can't get hold of me, they call my husband. Last year I registered on the The DMA National OPT OUT Database, but this is not honoured and I still receive unsolicited phone calls. Calling me is irritating, but calling my husband is unacceptable, embarassing and a breach of privacy. Izwe informed me that they buy the information from Information Capital and that they cannot be held responsible, which I find rediculous. On Friday, 27/02 I requested the Izwe call centre agent to remove me from their calling list and was assured that it was done and I won't receive any more calls. Surprise, surprise ... at 09:37 today, 02/03 they called agaiin. Stop harrassing me and don't call my husband!
