Bad service

Terrible service and it seems like people there don't know what they are doing. Noone gives you an answer. I cancelled my contract 30 days in advance and 5 days later they haven't released my line in over 6 days I have phoned every Department to ask for help with release of the line and have spent over R500 on airtime and you are put on hold till the call drops. This is very unprofessional and I feel it is a sabotage for VOX to get me into retaining my contract with them but I will not as both their network is poor and customer service is very very poor. I am grossly disgusted at the level and type of service.
