Hi Jamiefmackay! 👋 welcome to the community! Thank you for posting and letting us know about your concerns regarding how to end you current services.
There's a couple of things to mention here so we can get you the best possible support.
1) If you are porting your landline number over, you need to have landline services active with both providers whilst the port is being completed. If this is the case for you, this may be why BT advised that you need to keep your services active. Once the number port is completed this should automatically close your landline services with them.
2) We can't access any other providers systems or account information so we would not be able to provide information about your final bill with them, or any early disconnection fees if there are any applicable. You would need to speak to any alternative providers directly to get this information. We would only be able to provide support and advice about your Virgin Media account and services. We also would not be able to check for you if all services have been cancelled on their systems on this basis, so if you have services besides landline you may want to get back in touch with BT directly to check!
3) Can we also check if this is something that was offered to you by us (VM) at the point of sale? There will be some changes coming in future regarding this process, however there have been no changes as of yet and our standard practice is that our customers cancel their services with us directly.
Please let us know if there is anything else we can offer help and support with 🌞
All the best.
