Imcompetence from One2one call centre and MTN

I have switched from Blackberry internet services to normal internet and data as I no longer have a Blackberry device. I did a sim swap at a Foschini store as instructed. I have waited for 10 days for my connection to the internet to be activated on my new sim, and the One2one call centre refers me to MTN while MTN insists that the One2one group need to activate it. I have been going back and forth for the past 10days now. I even went into a MTN store. They tried to help me out, however they couldn't do anything as the call centre agents told them to refer me back to One2one at TFG. I want to cancel my contract with One2one because they are so useless and pathetic, but they say that I will lose my number and cannot port it to another network. When I complained to the manager at the one2one call centre, he said it would take between 2 to 24 hours to resolve and he cant help me further. ABSOLUTELY HORRIBLE AND *********** CUSTOMER SERVICE FROM BOTH MTN CALL CENTRE AND ONE2ONE!!!! Llewellyn Narraidu
