MTN ARE *******!!!

I opened up a contract with mtn last month - R399 for 120gigs per month including the router. I got assisted by a gentleman by the name of "Lux" at Baywest Mall in Port Elizabeth. He was nice enough to not charge me an "admin fee", and I collected my router on 30/09. I was advised that I will only start paying from the day I collect. I asked Lux when I would be receiving my first tax invoice as my work reimburses part of the payment as I work from home nd I need it before the debit order goes off. I selected my debit order to go on 25/10 and he advised me I will recieve it around the 11th or 12th of October. First of call, I called the customer service line today only to find out that my statement/invoice will only be available next month which is COMPLETELY unacceptable as my first debit order is going off this month so surely I should recieve one this month?! And I am now inconvenienced as my work will only reimburse me once I submit my tax invoice to them...the agent advised he will escalate and I will recieve it on 20/10, so lets see if that comes through?! SECOND OF ALL I GET TOLD THAT MY DEBIT ORDER THAT WILL GO OFF THIS MONTH WILL BE AN AMOUNT OF R1000 as Lux never loaded my contract as a special, but rather the original amount!!!!!! And they want to charge me for before I collected my router. I will NOT pay over R1000 for something I did not sign up for l, this is COMPLETELY unacceptable. My first contract through MTN, and I will NEVER recommend them to anyone:-@ :-@ :-@ MTN better get someone to contact me ASAP and before this incorrect debit order gets taken, to rectify this issue or else I will take this further!!!!! ***
