This number looked like a scam, or some marketing call, but in case it was a work number, I tried to ring this number back, but it said " not connected ".
Must be a scam.

Said they wanted to speak to the business owner. I said they are not available and who is calling - he then hung up!

Caller: obviously a call centre

wanted to discuss "online visibility" with the owner of the business.hung up when i refused to identify myself or the owner.

0855504584 when asked who am i speaking with, he replied, "Its a private company sir, thank you" & hung up. He had an indian accent.

Caller: Dont know

When called back voice said not connected must be a scam, no message left.
