Charging me !

To whom it may concern. I am utterly disgusted & disgraced with MTN @ the current moment! Yes, I am in the wrong I am in arrears with my account but I have been conducting it at the moment( fairly well) and I have been paying . Now let me tell you even though I AM PAYING I am still receiving phone calls and sms CONSTANTLY! Today I receive a phone call from Mtn Consultant not to sure what her name is but she was RUDE AND CHEEKY, when I asked her why do I keep receiving phone calls I got attitude and she said to me it is because I HAVE TO MAKE AN ARRANGEMENT FOR THEM TO DEBIT but I have been paying regularly now and have not missed a payment , SO she gave me lip and said well I AM THE ONE WHO IS PAYING FOR THE PHONECALL WHEN THEY PHONE FOR OUR ACCOUNT ! what a flipping cheek she has to say that me , I should be going to small claims court or be putting up a fight against them as I am trying to pay my account finished and yet they ADDING MORE! WHAT A ******* OF A PLACE! I am so livid with MTN once that account is closed I will never give you service nor even recommend anyone to come to you !!!! I have never felt more ashamed in my life yes I am in arrears but I am making payment now and yet MTN STILL CHARGES ME! !!!!!!!!!!!!!!!!!!!!!!!
