Sending a letter seems to be one of the more successful ways to cancel, as reported on here. Doing so carries a certain legal weight and using a tracked/signed for service means it is hard for VM to wriggle out of it.
You can cancel your services by post as per info below

Use a first-class, signed-for delivery service. This will give you a date/time of delivery when you gave VM your 30 days’ notice to cancel. Also keep a record of the tracking number.
If you cancel during a minimum term period VM may charge you early disconnection fees.

You can share your unhappy cancellation experience with OFCOM.
They launched an investigation into VM on 13 July 2023 specifically into VM's cancellation and complaints processes.
https://www.ofcom.org.uk/about-ofcom/bulletins/enforcement-bulletin/open-cases/cw_01275
Case ref. no. and an email at the bottom of the above page or submit with same info via the contact form

Submitting information won't help your individual complaint but it will contribute to the OFCOM investigation and it sounds like your experience is directly relevant to the terms of reference of the investigation.
