BAD SERVICE

I was assisted by a lady called P Moodley from the online department. I was dues for upgrade and she said she will assist me with that. On the phone everything she said sounded so true and convincing. I agreed and go ahead with the upgrade. She promised me that my 1st bill for the new upgrade will be august my current contracts ends july. That did not hapen because they double charge me on July and also on August they did. That was the 1st thing she said it will hapen and did not. Secondly she said she will close my previous contract and we continue with the new contract and she did not do that also. Now she is still billing me from that previous contract. I call her several times and still she can not fix this.
