This is a scam according to Peakofohio.com news

An out-of-town number has been calling residents & businesses claiming to be your local chamber.

The calls have originated from 740-401-7057.

If you receive a call from this number, it's NOT a local chamber.

7404017057 call multiple times during the day then hangs up after a moment.

I answer the phone with the name of our company. Female asks me if this is XXXXXX? Yes it is. Is So&So still the owner? I ask who this is. She tells me Maria with the Chamber of Commerce. I ask her which County and she tells me the American Chamber of Commerce. She then hung up. Calls from 740-401-7057 and when I call back it rings once then goes to a busy signal.
