On checking the tel no, and googling the number, this number comes back as

Unfortunately, topics about calls from these 0800 VM sales numbers get mentioned on here very regularly.
This one (about another 0800 VM number) stretches to an impressive 26 pages

You have no way of knowing whether the call is a genuine one of not due to the possibility of scammers faking the caller ID. In the above topic, a number of the posts are certainly complaining about scam callers, another group are certainly complaining about VM sales agents and another group have no idea if they have been called by scammers or VM.
Since you, as a VM customer, have no way at all of telling if the caller is genuinely VM or a scammer, then the idea of giving out any personal/security info to an unsolicited caller is a total non-starter, so in my view you were 100% correct to end the call.
If you don't want to receive sales and marketing calls from VM, then opt out of marketing preferences in 'My Virgin Media' and also sign up with the TPS. If you have a phone which can block numbers then start blocking the VM sales numbers when they come in. Sadly there are a lot of these 0800 sales numbers you might have to block and opting out via MVM doesn't always guarantee the calls will stop.
