Harrasment

My medical bill was not paid initially by my Medical Aid without my knowledge. One day I started to get threatening SMS's and thought it was spam, but it did not stop and eventually I called the number and found out what it was about.<br> Long story short, the account was settled by my Medical Aid and I send MBDCS 3 mails already confirming that it has been paid, but still the SMS's keep coming. Try speaking to the guy on the other end, apparently they can not read or hear.<br> <br> I told the guy my bill has been paid and I have send prove, but he is arrogant as hell and he does not even know who I am.<br> <br> These guys are absolutely pathetic and is harassing me. To who can I report them to?
