settling my account

I have a contract phone with Mtn which l bought from Mtn direct from a very nice guy who assisted me but for the past month l've been wanting to settle my bill but l cannot because Mtn direct workers are on strike apparently! Am due for an upgrade and l need a phone but there is no one to help me. I went to an Mtn storein four ways and they said they couldn't assist me.. A month is just too long really.
