Telkom LTE customer charged for unauthorisservices

The services was connected in October even though the contract was signed 24 September 2014. I did not get any bill from Telkom until December 11th when I was querying the first debit order of R1782 that Telkom processed on 20 November 2014. Telkom discovered that they have been capturing my email address incorrectly on the system. I signed a contract for R449 per month for 10 G day and 10 G night for 36 months (B2C). I specifically asked NOT TO HAVE ANY spend limit. Telkom agent on the helpdesk then confirmed that they have incorrectly captured a spend limit of R1000 pm and another R1000 will appear on the December bill. I was unaware of the spendlimit and was not aware that I have been using it. The reference numbers and case numebers on this matter are Case ***3
