Not what the agreement was

R99 for 2GB contract which was recently upgraded. On 2 September R1520.20 was deducted. It was for the month of July. My agreement was that once the 2GB is finished the internet will cut out. It didn't. I went to Mtn headoffice in Bloemfontein on 7 September 2015 since the small branch in Fleurdal wasn't able to help me. I was helped by a nice guy. He sent an enquiry to the technical team. I had to phone on 10 September to check for an update. Once I phoned Mtn they gave me another number of another company and said the upgrade was done via them. So I phoned the other company. They referred me back to say the upgrade was done by Bianca at Mtn upgrades. Since the upgrade was done over the phone I don't have any information regarding the contract. I am looking for the recording of our conversation during the agreement of the contract. I am running in circles. Its costing me time and money.<br> Also.....my internet was cut off today 11 September. It said my data limit have been reached. When I went to Mtn again for a check up on my enquiry they told me that I have 1.6GB data left. My internet is still showing the same message. I am very frustrated!!!
