MTN keeps on billing de-activated/cancelled service!

I cancelled my MTN Contract + Phone number with MTN in January/ Feb 2019 at the Paarl Mall branch. I have not used that cell number or sim or data since January / Feb and as far as I am concerned I DO NOT HAVE A CONTRACT WITH MTN!

For some reason, MTN has not cancelled the service on their side, and has kept on billing me for a service and Data that I have NOT USED!! Now they have debt collectors who are threatening me for a R4000+ bill for a phone number that has not been active for more than 9 months, I have NOT used their service, nor any data - but they kept on Billing me - even though I have NOT Received ANY INVOICE since the end of 2018!!

It is not the client's fault if their customer service is so pathetic that they do not cancel contracts when clients request them to terminate! My contracts expired in October 2019 and December 2019 respectively and I have NOT used the 083 *** number since January/Feb of this year.

Please amend your records accordingly and advise MTN to stop harassing people who are NOT CLIENTS of their service any longer!
