Order cancelled without informing me

On 23 June I received an email promoting a special deal of a 10Mbbs ADSL line with landline rental, modem/router and a DSTV Explora for R699. That afternoon I called 10213 and, after spending 40 minutes on the phone with a lady, signed up for the deal. I received a reference number to confirm that all was complete and was informed that I would receive my Modem and Explora within a few days and my line speed would increase in a few hour. After hearing nothing for a few days, on Saturday 27th I went online to My Telkom only to discover that the status of my order was CANCELLED. I called the call centre and, after holding for 25 minutes, spoke to another lady who gave me the name of the original person I dealt with and her direct number so that I could ask her directly why it had been cancelled. Of course, the number is either busy or not answered. Called the call centre back to be told it was outside of office hours. Spoke to them again today and was informed that the DSTV Explora is no longer available - EVEN THOUGH IT IS STILL OFFERED ON THEIR WEBSITE!! I want to know why my order was cancelled, why I wasn't informed and why I was offered a deal that is no longer available.
