Scam?

[Mik2987]

I have been contacted by people purporting to be representatives of O2, trying to upgrade my Sim. when I questioned their legitimacy because of some puzzling messages and instructions, they accused me of failing to cooperate and threatened to block my numbers, then cut me off.  I need a legitimate telephone number to call to check a. that I have not been scammed and b. that they are not going to 

block my SIMS as they threatened to do.

I gave them my email address, date of birth, and place of birth before I realised they might not be genuine - it was when they started asking for the one time activation code that I became suspicious.  Is there a danger I have opened myself up to other scams in relation to other accounts and can anyone advise on actions to take in addition to reporting the scammer number.

@Mik2987 Unfortunately you've made a huge mistake.

If you think you’ve been the victim of fraud – whether it’s because you’ve given details to someone over the phone, or clicked on a link in a suspicious text or email there are things you can do:
Contact your bank if you think you may have given out financial information. They can help protect your account and stop transactions.
Change your account and online account passwords. Not just your O2 account. All of them.
Forward fraudulent texts to O2 for free on 7726.
Contact Action Fraud on 0300 123 2040.
Call your Virgin Media or O2 customer services number if you think somebody’s taken out a contract using your details.
Virgin Media customers can phone 150 from their landline or 0345 454 1111 from any other phone.
O2 customers can call 202 from their O2 phone or 0344 809 0202 from any other phone.

You can block the number that called you, or any number you think may be suspicious.

Change your O2 password too and any others that use the same details.

Notify your bank if you haven't done so already.
