01822 300017 Negative Who called me from this phone number?

Man with Indian accent claiming to be from Sky calling to tell me my Internet speed was slow. I played dumb to waste their time for as long as I could, upon being called back after a disconnection, I answered the question of "what is on your screen?" with "I'm just searching the number you called me on in order to call back." at which point they seemed to give up.

If you call this number the recipient or an machine terminates the call, I stupidly phoned the number from my other mobile and now received silent calls on that phone. I've blocked number on both phones.

Indian man from “O2” wanting to sell me a new deal, Clearly a spam

Wanted details of a card reader. Did not intoduce himself properly, poor english. It was obvious it was a scam.

Got a call from this number and a man with an Indian accent is on the other line claims he is from EE telling me that my "credit score" is good and asking me if I want an insurance. Number doesn't seem to be from EE (https://ee.co.uk/help/help-new/offers-and-services/other/phone-calls-from-our-partners), definitely a scam.

No message left Never heard from or of before

Called this afternoon but English was so poor I had difficulty understanding him but I was getting 30% off something. He hung up when I asked where he got the number.

Called me this afternoon, couldn't answer but no message left. No idea who it was but doesn't look like a private number and I know no-one in this area code

Said was EE and had all my details

The caller rang me from this number and immediately hung up on my answer.
