Ripping us off again due to their own incompetence

So I app**** on 5 May 2017 to have my LTE cancelled. According to the Telkom rules it was supposed to have been cancelled 21 working days later. It was only cancelled this month after I had to raise an issue on this forum which went ignored, raised the same issue on twitter and after some direct messaging it was cancelled. I was told the order would be back dated when the account was to be reconciled as I has now paid for at least 2 extra months due to Telkom incompetence. Now I get my latest account and they have only done a recon since the date of cancellation - nothing has been backdated. When trying to explain and despite having this in writing from Bill on the twitter account I just get told "Its been cancelled.." - Yes i know this - you miss the point - NO RECON HAS BEEN DONE!!!! but you were not shy to slap on a hefty cancellation fee... To quote the conversation "Hi James, the order was backdated and should reflect on the next invoice. The account has not be reconciled as yet, so we cannot check this for you at the moment. However, if it does not reflect, please dm us and we will certainly assist.^Bill" As usual I am sure this will go unanswered and you wont really care about any customer service.... Thanks for nothing Telkom - have a great day...
