ONLINE UPGRADE NIGHTMARE AND USELESS CUSTOMER CARE SERVICE

I app**** for an upgrade online for my 2 contracts that my wife and son use on the 7th September. Received various emails from upgrade@... and mtnsales@.... *** both mtn and Mondo requesting documents that I keep sending. I explained in my one email that during the day I dont cant have my fone on me because of work safety reasons, and they wont let my wife handle anything because she not the account holder. I have still not received proper feedback what the status of the upgrades are. And no one responding to any emails. WORST SERVICE EVER!!!!!!! ITS ALMOST BEEN A MONTH NOW
