Thanks for your post and welcome to the Community. It's really great having you on board with us in the Community.
You've not really given alot of information in your post however unless you are expecting a call back then it's safe to say this would be a scam and it's really great that you've been able to recognise a scam when you hear one.
Make sure you are reporting the calls to Action Fraud UK here: https://www.actionfraud.police.uk/ so they can get as much information as possible to close the scammer down. It's also worth registering for the Telephone Preference Service here It is the UK’s only official ‘Do Not Call’ register for landlines and Mobile numbers and is free. That should help reduce the number of calls you receive.
