Utter Incompetence!!!

I have been a loyal custormer of MTN for as long as i can remember, i dont know any other network but MTN,but for the past 3months everything has changed. the level of service from the agents to the team leaders is absolute ignominy,my acc was in arrears for a month,been trying to make arrangements with MTN for the last 3mnths to deduct the arrears amount,but to my suprise they cant execute a simple instruction, they have been going late into my acc,which has caused me bank charges for the past month,I contacted the call centre about 8times if not more but no one was able to assist even their TEAM LEADERS,just last week i called in requesting to speak to the department manager,call wa placed on hold for 30min with no avail,this month of December i made arragments way inadvance with MTN to deduct my acc on the 21st December as my salary was paid in on that date ,again with arrears amount.MTN decided to go into my acc this morning after a clear instruction,again causing me bank charges,I GET PAID ONCE A MONTH for crying out loud.<br> I dont even have the energy to call in and quiry the bank charges because i dout if ill get assistenc<br> cell number in question is:***
