Unfortunately your number has been chosen as the one by some scammers @Dave-the-shirt
When they call people that choose a number to show on screen as who they are, and it sounds like they have landed on yours.
You have two options - hope that they soon move on and keep your number (but you might get calls from people saying you have called them), or contact o2 to change your number (but you will have to get everyone who has your number to change it) - and there is no guarantee that your new number won't get chosen at some point too!
Please note, this is not customer services and we cannot access your account. Do not publish personal details (email, phone number, bank account).
