Lack of Proper advice

In june i needed to upgrade one of 4 contracts with CellC. This proved to be a very problematic process. The issue eventually got sorted out after much hassles. Again on the 23 June again I tried to do some business with CellC and it is proving once again to be a mammoth task.<br> I called the call centre. I explained that i knew i was not due for and upgrade yet and i proposed that i would buy out the rest of my contract period and that would put me in the position to upgrade. The agent agreed that it could be done that way. She gave me the settlement balance amount and advised me that i should pay that and then we could move forward. She neglected to inform me that that would mean that this contract would come to a complete end and that if i were to appy for a new phone it would be a fresh application with credit vetting etc. Had i know that i would not have ended that contract. I would have waited for the time when i could do a normal upgrade. Cellc are now refusing to give me a new contract because i have an unpaid account elsewhere. I don't understand this since my account with CellC for the last 16 years has always been impeccable. I strongly believe is not informed correctly.
