Port out nightmare

I have been trying to port out from vodacom for the last 6 weeks. I have called the call center to unflag my number to port our. They will log calls with port team but will cancel my request. I went to Telkom to see what is the problem and was told that vodacom is refusing to let go my number. Am sick and tired of going up and down to telkom only to be told that vodacom is refusing. I want to port out as vodacom is abusing my data.
