Telkom/8Ta Useless and *******!!!

Mid August my phone line and internet connection was wrongly disconnected, I was on an Unlimited contract. I had made payment on the 28 July, when I called the call center to enquirer why my line was suspended I was told due to no payment, when I sent proof of payment even after they said they could see that payment was made I was told I had to wait 72 hours, so I waited, and nothing, after endless call center calls and in-store visits with no success I tweeted the CEO @Amith081 who did not reply just got the call canter to contact me. Eventually at the end of August I got reconnected, but I still had to pay for the full month!! My contract ended that month and I requested to have my number put on prepaid so that I can port to MTN, I have an sms from 8ta saying that my number was turned to prepaid on the 1 Sep, I then ported to MTN. Now I am still receiving invoices for Sep and Oct and getting calls that I must pay!! I'm no longer with 8Ta!! No one seems to want to assist!! I have kept all communications, emails, tweets, sms, If I do not get assistance I will go to all newspapers and Cart Blanche!!!
