Thanks for sharing that information, I can see from googling that number that it could have been from BT. Are you one of their former customers? If so, I would give them a call on 0800 800150 just in case they needed to chat to you about anything in regards to your former account.
If you have not been a former customer of BT then it could be a sales call from them or a scam call. I have your details now so if you are charged an amount for this, I can look into it further for you. The fraud team are currently on lowered hours so it could take a while for them to get back to you, thus, I will be happy to investigate it as a complaint for you.
Keep an eye on your bill for me and come back if you need further help.
