Telkom And Wns Billing enquiries

I have had adsl for 2 years and decided to cancel my contract once my 2 year period had come to an end . I followed all the processes and received a confirmation email to say it had been cancelled successfully . I gave the notice period and waited for the final bill . I even confirmed with someone in store who advised there will be no penalty charges as my contract had rightfully ended . I then noticed that my adsl was off as agreed on the 10th October . My last payment was made .I then received a new bill for the period of November to December . With this is called in to 10210 and spoke to a manager called Wayne . He told me he would email me with confirmation that i need not to worry . I waited a week and called again and spoke to Wayne who apologized for not sending an email and advised he will email me asap . It has been another week , still no email . I also noticed that my credit scoring has dropped because of this bill . I was given an email address by wayne who says he is situated in the P.E center . which is wns as he stated . The email address given by him was bogus because no email sent by myself could be successful. Is there anyone who will sort this out as i hate being labelled a bad payer unfairly .
