Bad service received from Telkom

Telkom debited my account on 19 June instead of 20th which I signed for. I complained about this because the bank charges me an honouring fee since I did not have enough funds but no one took interest in this. After a month of several follow-ups Motlatsi from accounts called and told me that they sent me an sms before debiting my account she never wanted to listen to me and she put the phone down without a good bye. Called again and spoke with Sibongile Malinga who told me to send an email but to date she still hasn't even acknowledge the receipt. Called again spoke with Shaunese Beukes who said she will put me through to the manager but she kept on hold for 1 hour after which she dropped the call. I called again and I spoke with Thato Mowatse, this lady at least she had a good customer service and she nicely referred me to his manager Mr Mohammed Ally. I discussed this matter with him and sent him an email on 13 August 2015, he promised that they will investigate the sms story to find out if I was notified. But what suprises me is that to date he has not provided any feedback. When I call to follow there is no feedback (***8) . This is the worst service ever in my life.
