Caller: Unknown scammer or cold call

Another call centre scammer/spammer. Heard the background tell tale noises before we hung up. Rang 5 times in 30 mins. Blocked.
we are NDC register.
Caller is one of four things:
1. Scammer
2. Unsolicited cold caller (illegal to call someone on DNC register)
3. Charity seeking donations
4. A government initiative (eg Solar panels)
Given they called back 5 times in 30 minutes it is MOST likely they are a scammer. Cold calls for other purposes USUALLY don't try more than twice.
Number is now blocked.

Missed call on my home phone, which is on DNC. Called them back and heard woman's voice in noisy environment, saying she's from XXX Property.
Not sure whether it's a genuine no. compromised by scammers, or the no. itself belongs to scammers.

called twice from this nbr, pretending to be "solar panel" service people

A week after I blocked this number they called another 63 times (!!) this morning, auto dialler obviously.

SCAM CALL

Called 3 times. all within an hour just now. Targeting lunch time. Thanks everyone for comments. Calling home phone. Thinking of getting rid of home phone....haha

Can confirm this number spams calls from some sort of call centre.

Block them if possible.

3 calls today, now blocked.

Called 3 times in the space of 2 hours. No message ever left. Called number back - after blocking my sending number - no answer and went thru to v/mail and left them no message.
Highly improbable that it is anything other than a spam/scam number.

Many calls unanswered but no messages left. Most likely a scam.

Identified as Elena from a “local solar company”. Would not tell me where she got my number from. She hung up on me.

Rang 3 times when I asked who was calling they hung up

Four calls today.
No message left!

Rang 3 times and when answered waited 3 seconds and they hung up

Called me twice so far today, I didn't pick up as he's a serial offender........scammer I suspect.

4 calls in a week no msg left

3 calls from this number - all with no message. Clearly a scam!

I didn't pick up the call but called them back. No ring but asked to leave a message. Hiya has identified it as potential fraud.

5 calls from this number today..... never left a message.
