Compare the calls in your bill that were listed as chargeable against this info. If it all checks out the calls you were charged for should be inclusive and never overran the hour mark, then you can confidently discuss it with VM and ask for a credit/refund regarding those charges. By calling into 150 then go with option 1 (Billing) -> option 5 (All billing related queries.)
You can also query it via the Contact Us page between 8AM to 8PM from a desktop or laptop device: http://contact.virginmedia.com/ -> Account and Billing -> My Broadband, TV and Home phone bill. Click Chat Online. It may say all agents are busy, if so, wait for a chat prompt to show and run with that or refresh the window every couple of minutes to check again.
Those are the two options to go with as billing matters aren't dealt with via the community (due to the DPA.)

Re: I have talk unlimited and yet I am still being charged for calls
Thanks for posting and welcome to the forums
You've had some fantastic help already from our community and Superusers
In order to check that you have not been charged for any of the calls that are part of your current call plan, Talk Unlimited, you can take a look at your unbilled and recently billed calls via My Virgin Media here, or by giving our team a call on 150 or 0345 454 111 as for security reasons we are unable discuss billing via the forums.
The calls that are free as part of that plan have been advised by @nodrogd above and that information given is totally up to date
If there's anything else I can look at helping with then please let me know
