NON RENUAL & CANCELLATION OF CONTRACT

On 11 August 2022 I cancelled 2 x data lines via dialing 135. I payed the two month cancelation fees as required. It is December 2023 and several e-mails; telephone calls that I have to hold on for 30min and longer; plenty of messages on Messenger = I am still being billed for data lines that I am not using. Till today know one from MTN has contacted me regarding this. Local MTN outlet can not resolve this problem, they revered me to phone 135 of customer service to resolve. E-mails response is = "ISSUE HAS BEEN RESOLVED" Messenger response is = KINDLY BE ADVISED THAT WE HAVE ESCALATED YOUR QUERY.........." Due to the above, I can not upgrade my current cellphone package that is due for upgrade in Feb2024. POOR CUSTOMER SERVICE FROM MTN!!!!!!!!!
