No Invoice&Statements but want payment!!!

It is the 6th of February 2015, and after many calls to the call centre, I have yet to receive my invoice for the 7th January 2015. Yet MTN is threatening to cut me off if I do not pay. Yesterday, 05 February 2015, I eventually got my Itemised Calls sheet, but no invoice and statement to detail what else am I paying for. <br> MTN, please answer me this. Would you pay a supplier of yours an amount of money without first having the invoice so you can check that you are paying for the correct things and not being overcharged?<br> I bet you your answer would be no. So why are you expecting me to pay without me having my invoice, so that I can check if you are charging me for the right things (which by the way you made mistakes on my December bill which should reflect on this invoice that I have not received, funny isn't it???). Yet you are threatening to suspend my service!!! Is that fair??? After I have struggled for more than 2 weeks, only to get a my Itemised Calls sheets!!!!<br> And tomorrow is the 07 February 2015, when my next invoice will be generated...So Now What??? Get back to me with an answer!!!
