Said I had applied for solar in March which I have not and was calling about my application

Many missed calls from this number. When returning the call, it was a voicemail saying 'please leave a message' then it goes blank. Another call back and they pick up and no one responds, but you can hear people in the background and they then hang up.

Getting call regularly from this number-telling that I have enquired for solar panel, which i didn't.
