holding my i phone hostage

i am absolute disgusted by the treatment from mtn its now months since my i phone was sent for repairs and yet every month as per agreement on d<br> the debit order day i meet my obligation and you get your money....i want and demand my phone fixed and give you 7 working days before i send your new ceo an email and go to the ombudsman.....<br> p.s forget the data that i have forfeited in the mean time, just bring back my phone fixed and i cant wait for the contract to expire and move on <br> <br>
