MTN-the biggest mistake you will ever make!!!

I work in a telecommunication centre as well and I have never seen such bad customer service in my life! I don't know if it is your staff or the higher management that cannot assist customers effectively and ensure that their queries are resolved. I am so disgusted with the calibre of people that work at MTN i am not sure if the training is adequate at the moment, well I could be wrong it could be the agents then again it could be their managers who have not been trained adequately not forgetting managers are led by directors who in this case have no focus on the customers such as myself who are at the bottom of this chain. From your staff not taking down the correct details for my banking, not taking my calls, not debiting me to double debiting me right to managers not returning my calls. All I'm asking for is that you call me back to resolve my query and give me what I need which is a letter stating that I am not a bad payer because YOU GUYS did not take out the money on time. I am very upset and disgusted with this behaviour and the calibre of people that you have working at an established business.
