Pathetic Service and harassment from VOX TELECOM

I purchased a TV through FNB and i was given 1 terabyte of data with the TV. I signed up online and received the service for a couple of days. I then received a call from VOX Telecom harassing me for my proof of purchase for about 2 days and threatened to cancel my service which i rightfully paid for. I work 8 -5 and i took some time out of my day to get the proof of purchase from FNB. When VOX was given the proof of purchase, they rep**** to me saying i don't qualify for the service which i already received and paid for and i was harassed for 2 to 3 days for a proof of purchase, did you not know i did not qualify before harassing me? They also disregarded all my complaints and kept closing my emails. i have tons of reference numbers. The lady at VOX specifically said i can complain on hello peter, the complaint will come through to her anyway. How ridiculous is this? The people working at VOX Telecom have no idea what they are doing? The lady even sent me internal process document used for internal staff, how unprofessional is that? I need to speak to somebody higher than this woman in VOX Telecom who understands customer service. I want the service i paid for as well...!
