Asian sounding male used my surname and knew I had solar panels. Asked when they were last serviced by a professional. I then hung up. I had a similar theme call 29/11 from. a female Asian from number 0458 553 966. Obviously scam calls

O/S Caller - SPAM - Wanting to quote for solar Panel clean - they called 3 times with the same request. each time I said to please don't call this number.. Eventually I had to block the number completely.

I had 3 calls this afternoon within 1 hour!! I didn't recognise the number, so let it go to message. Surprise, surprise - they didn't leave a message!!!

I know they are scammers but still they ring. I hang up.

Missed the name, but he asked me by name when I had last had my solar panels serviced and cleaned.
My landline is DNC.
It wasn't a robo call, as it went to my 30 second voice-mail timeout. There was one empty message.
Could have my name and number from my panel retailer or elec installer.

Saisw that his name is David. Asked if I had Solar Panelws. Said thar he is in my area. Say that he is from Green Something. I have never heard of him so I don't want to take a risk. I will contact Plumbers that I know of and trust.
