Harrasment

I am being harrased by Nedbank keep asking me for payment or contact details for the owners of a SOETBOS LANDGOED. I dont know where they got my number from or how I am involved in such an estate. I asked them for the offer to purchace where my name and signature is on the form so that I can take occupancy or ownership of this so called SOETBOS Estate. The person I spoke to today drop the phone in my ear after harrasing me about this ESTATE. PLEASE PLEASE PLEASE remove my name and number from your system or give me the keys and deed to this estate.
