Called and hang up, when calling back this number it says that it is not connected.

I received a call from this number and was unable to answer but no message was recorded. When I tried to call later it went straight to message but the message service has been disabled, as in you cannot leave a message, not that I was going to give any details.

Android on Samsung tf said potential fraud so didn't ring back or answer

Called back - number not available

Shows up on smartphone screen as Potential Fraud, so did not answer it. No message left.

Caller: Asian call centre

Difficult to understand but I think was someone offering 1.8% interest rate on home loan. Hung up as sounded dodgy and too hard to hear understand what they were saying.

I answered with my name - accented male then said hello and my name and said it was Peter. I asked where he was calling from and he then hung up

Caller: Spam morgage finance

Called initially saying he was from "mortgage group", somehow he knew my name, said he called me last year (which he didn't) then when I asked him again he said he was from "Easy mortgage". He was going on about how banks have lowered mortgage rates and started asking details about my mortgage and saying he would email me through a some details about changing my mortgage. I hung up, I think he was just trying to get bank account details
