Fails to do simple requests!!!

In January when I decided to go from a Prepaid account to a Top Up contract, one of my requests was for them to keep my old Prepaid number and just have it prompted into a new Top Up account. But for some reason, they fail to do that simple instruction. We argued many times to fix it, but its as if they can't. When I got my old number back, it's still prompted as a Prepaid account. And when they activated the contract onto the sim card in the new phone, they gave me a different number and they deactivated my Caller ID privilege(which was included in the contract). The contract is under my mother's name, but even though the helplines said they understood the issue (after they directly spoke to her and me), for some reason they fail to fix it. I decided to refuse to mention the branch's name because they understood my issue, explained the issue to the source many times, but no resolution was returned with a 100% satisfaction.<br> <br> Why???<br> <br>
