Unable to cancel the contract due to lack of response

Unable to cancel the contract due to lack of response. On the 3rd of March, I wrote to mweb asking to cancel the contract by end of March 2026. I received an automatic response that they will respond to me within 24-48 hrs. I did not receive any call nor response to my email. I followed up via a phone call, i waited more than 30 minutes on the call until i ran out of airtime. Today, 16 March, i called them again, to follow up on my cancellation request. I waited on the call for almost an hour, after which, my call was disconnected for unknown reasons. I am of the view that Mweb makes it impossible for one to cancel their contract despite their service being poor. I would like Mweb to release the link and provide the cancellation reference urgently.
