Who called me from 03303035315?

They rang me at 10.20am yesterday. Pretending to be 02 and asking if I'm happy about my plan. What a load of rubbish. They think if they quote my plan and price at me that I will tell them all. Absolute idiots. If it was 02 they would be asking me for the information as a security check, not spouting it the minute I answer the phone. Told them I have no idea who I'm talking to and that I refuse to speak to them. Then I hung up and blocked the number. Don't take calls from this number.

They called me today pretending to be O2 but said I'd to reply to their email. I don't have email on my phone and O2 has never asked me to do this before. I remembered the scammers need me to click on an email so I didn't comply.

FAKE O2 Rep trying to scam me i hung up as the call seemed a little off and then i contacted O2 and the said it was 100% FAKE and to Block them which i did

keep getting multiple messages from o2 app saying they will be calling me and i answered once and they were offering me a deal, i told them I don't need a deal right now and they said thats fine and they will call back in 2-3 months. But they are still calling me a few days after, I blocked thier number after a few days and still recieve a message saying they will call but don't actually get a call so best advice is to block the number. I think it's a third party company working on behalf of o2, but even after saying that, be careful, companies shouldn't be spamming their custoemrs, thats one of the worst things to do in customer service, contact o2 through their contact information on o2 website or look for deals yourself online.
