Terrible Service

I upgraded a contract in April which activated in May.<br> Since then i have been trying to convert the package from a contract that once your allocated airtime and data is used, is then billed on your account to a top up contract (uChoose)<br> The forst time i called they advised i need to have the contract activated for 3 months, which i waited for.<br> I called again the end of august and the consultant said they could not do the migration as the system would not allow it. they logged a callto see why this was. After 2 weeks they still did not get back to me and i once again had to call them. they then advised it could not be done and that i should wait. I told them i am not waiting another month to do this as the 3 months is now over. <br> a call was logged to the migrations department to get this fixed and said they would call me back (on a number i asked them to) to let me know once it is done. today they tried to call me on a different number and then just sent an sms saying that i must call to do the migration.<br> once again i called and when the consultant tried there was a cost of over 1700 to migrate<br> i asked why it costs so much and the person said that it is what the system says
