Upgrading nightmare

Since MTNSP took over my account from Nashua, I have had nothing but problems.<br> When I did my upgrade, I was told that the only way I can get the phone I wanted was to get a more expensive contract. They refused to simply let me pay the difference.<br> At the end of the month, my account got suspended because my new contract is suddenly more than my credit limit.<br> The credit department says the shop should have checked.<br> The shop says they cannot check, and I should have checked.<br> I did not know about this credit limit, else I would have checked.<br> BTW, it takes about an hour of holding on to get someone to check your limit.<br> I spoke to MTN Saturday, Sunday and Monday (today), and each time they promised my account will be reactivated in the next 24 hours.<br> <br> So is short:<br> 1. I was forced to upgrade to a contract I did not want in order to get the phone I wanted.<br> 2. This forced upgrade sent me over my credit limit, which no one bothered to check or inform me about.<br> 3. My account is still suspended, even though MTN has happily deducted the money from my account.
