**** service at telkom chatsworth branch

Last year november I upgraded my contract at chatsworth branch the sales agent was Munilas the upgraded contract was R199.99,however monthly I am receiving R350 ,I called their so called customer service to capped the contract at R199.99 . They primised me its capped at agreed amount ,but the bill continues to come at R350 . I called again the guy on the phone told I got two contracts the old contract is still billing me since it was not cancelled and new upgraded contract thats why the bill is R350 but the Munillas guy who was enrolling me on the upgrade he did not say I must cancel the contract ,his advice was the old simcard is blocked and the new sim will be now used .Now when I ask the call centre agent he said I must go to any branch however in pavillion branch they say I must go back to chatsworth branch. I went on 12/05/2018 the guy who was helping was rude and ****** he just jotted number 180 in piece of paper and told me they dnt deal with such issues at store level I must call that number billing must sort it out,when I ask for manager he said manager is not in,and when I insist he finally called the manager who introduced him self as Javed Khan who also was no help they could not even assist with cancellation because the was no ID but driver licence was presented the refused to assist .telkom chatsworth branch has bad customer service and ****** manager and agent his name was Niek his ****** comments shou
