Settlement letter

I'm really not happy with the customer service which will cause my kids to go hungry. This is very very bad. I've been asking for a settlement letter so I can close the account and the matter has not been attended to. I needed to have submitted this letter as a matter of urgency yesterday but when you try to get hold of them you end up getting your airtime finished but they have the guts to send communication that you haven't paid your account. Lewis I'm begging you to send my letter today!! I need to submit this letter as a matter of utmost urgency......your bad service is not nice, we also provide services but make sure we give people the best service, I'm not happy and would never recommend anyone there!
