********** Cellphone Upgrade

I'm a not a happy customer where i am,on the 19.03.2015 my debit order went through by R868.00 instead of R228.00 which i normally pay on monthly.I have learned from contact centre that i have upgrade in Jan 2015 with the i-phone how did it happen they said was done telephonically then phone was delivered to soweto Mfolo by the way this was the 3G contract which i was paying R99.00 on the monthly basis + i have another cellphone contract(Alcatel) which i pay R128.00 thus why my monthly debit is R228.00,how stupid can i be to take another cellphone contract.I'm also interested to know which number did they call because that was the modem number .<br> <br> After speaking to the consultant she advise me to do affidavid and fax it with my ID copy which i did,but what's frustrating now when i call their contact centre they can not really help me just to check how far are they with my case whoever is dealing with because i cannot pass security questions,my question again is did they not ask those security questions when they were **********ly upgrading my data contract otherwise i don't think i'll be in the situation i'm in now.<br> <br> I had to suspend my 3G, but i need internet as i do pay.<br>
