They won't let you cancel/leave

In April 2021 I sent an email to cancel me fibre subscription with Supersonic, the response email told me that one of their agents will be in contact to finalise my cancellation request. A month has passed without anyone at Supersonic reaching out to me. I had to wait 1 hour on the phone with them just to get a confirmation of cancellation.

And finally once my 1 calendar month notice has passed. Supersonic does not release my fibre line. Which I now have to call them in order to be told stories about a final bill which the cancellation department did not generate.

If anyone is looking to use Supersonic for their fibre offerings I would suggest they look elsewhere unless they are prepared to be stuck with them forever
