Upgrade - Unhappy client [#***6]

I've written before in regard to my upgrade on my MTN account, mobile number ***. I wanted to inquire how I can get my upgrade done as I'm working outside South Africa and I cannot get back home to personally sigh for my upgrade of my new handset and more importantly better rates for my MTN account.<br> I just received a very sort e-mail back from customer care stating that you do not allow for upgrades to be done if the account holder can't personally sigh for the upgrade. I feel that MTN is trapping me in a more expensive contract by not allowing me to upgrade my handset and my actual call and data package due to the fact I'm outside South African borders.<br> You have all my security details on your system and at any time I am able to scan and e-mail you all of my documents namely - <br> o Valid South African Passport<br> o Valid South African Green I.D. book<br> o Valid South African Driver's License<br> o And My police clearance report that I obtained in order to get my work permit<br> With all these supporting documents I do not understand why you cannot even try to assist a long time MTN customer and therefore forcing me to pay a higher monthly subscription to MTN
