Pathetic Service

My salary date switched to the 15th and my debit order always went through on the 1st day of the month. Now my phones is being suspended every month for the last 5 months. I've send numerous emails to MTN, I went to the MTN Shop so many times I can't even count anymore. I upgraded the 1rs of August and they told me at MTN that now my account wouldn't be suspended anymore because they changed the date to the 15th. My word is wasn't a week and again I'm suspended. And last week again suspended after they reconnected my account at MTN and said it would not happen ever again. I'm so fed-up with this I can scream through the walls.!!!! If MTN would just let me cancel all my contracts and I give back my phone I will be happy and rid of people with such bad knowledge of there work.
