Telkom didnt cancel my contract after request

I am disgusted with the lack of service and ownership from 8 managers which i have spoken to and escalated this matter to with no resolution, firstly u dont cancel my contract after i have paid it for two years and request a cancellation in dec 2014 at your canal walk branch, i got referred to your call centre and then referred back to the store about 6 times.finally i start escalating as you are now billing for your failed cancellation , you then proceed to tell me you need to separate my bills , so i must not pay it till u sort it out, i call u back 7 times , to ask you what my bill amount is that i need to pay to no answer.inturn you have sent my account to nudebt management.i dont know what i need to pay, you have failed to get back to me since june and when i call no one helps.not 8 of the managers i spoke to called me back, they all promised me resolution.i call today and an advisor tells me my account is written off and my lines are shut down. How dare you???i have e-mails and all the calls are recorded where you have **** to me and promised me to have this sorted.emails from your useless management.so give me a call. I am waiting since June.you better resolve
