You are the service provider for a company that is harassing me with daily hang up calls. The above numbers were supplied by you to a company registered as SASSA Grindrod bank in Sandton. I receive calls from them twice per day on my business land line. Upon answering the calls, they drop the call immediately. This has been going on for two weeks every single day. I ended up diverting the calls to my mobile so that I could pick up the callers number and then I had a Advocate trace it for me to Neotel as service provider. What can you do to assist me with this?
