Harassment by Standard Bank whilst under debt review

Hi, I am beyond fed up and frustrated with Standard Bank. I have been under debt review for a couple of years and have never missed a payment or short paid. They keep on phoning me claiming that the debt review has been cancelled due to non payment. My debt counselor, BB Administrators, have supp**** myself and Standard Bank with all the necessary proof of payment. Surely there must be a way for me to escalate this to a higher level because this is harassment! I just had a call from Lebo about 5 minutes ago, saying that they use an auto dialler and she couldn't really give me a proper explanation as to why I am on their list. She phoned me from ********** 003. I have had MORE than enough of this!
