telkom refuses to close my email account

Good day<br> <br> i opened a email account with telkom and instead of opening 1 acc they opened 2 email accounts. i have been emailing them since December 2014 to close this telkom email accounts as I no longer need this service, I have paid the R251.11 that they asked me for Feb and March although i never used the email accounts. I have been in touch with their billing department and still nothing I have received another bill of about R190.00 after i asked for the acc to be cancelled and closed. I have all the email correspondence and can get hold of the recorded calls. I need for telkom to close TELKOM EMAIL SUBSCRIPTION WITH IMMEDIATE EFFECT. And stop billing me as i requested. I will not pay a cent more for a service i am not using and struggling to cancell with them.<br> <br> please can someone resolve this matter and give me written confirmation thereof. <br> And call me, ***<br> <br> Lee-Anne
