Im out of words

I have two cellphones both on contract with MTN and I have used MTN for as long as I have had a cellphone. I am human and understand that machines and technology gives in every now and again so MTN would be no exception but my patience is on empty. I HAVE LOST AIRTIME, DATA so many times I cant count anymore, and you call their callcentre... either u hold on for ever or the phone hangs up. On that lucky occasion u get to speak to one consultant and just by your luck the agent is clueless and defensive so much so that at some point one even said I must drive to their offices at 14th ave on a Sunday afternoon because then they will sort it out, out of desperation I drove only to be told by the securities that I wasn't able to enter the place, spoke to her manager who was defensive and span some story wasting more of my time ... query still no resolved. I live in Naturena and when I get home I am as good as one who doesn't have a phone, my network I cant do anything no email, no social network, no calls at times and when people call me my phone is on voicemail.. you have airtime to buy data it says u have no airtime and spends the same airtym u reserve for data.. ******** AT ITS BEST!
