VVM hanging up repeatedly from their call center

SABC was notified in writing several times that I will not be making use of their services 2 years back. I explained that I am streaming all my media and that I no longer need to make use of their services.<br> <br> This was ignored and the matter was handed over to VVM whom simply hangs up if I tell them that I will forward the original fax to SABC.<br> <br>
