Got a call from this number this morning. I didn't answer because caller ID said California Call and I don't know anyone in California. The call went to voice mail, but they only left a 2 second message of dead air.
The caller told me the same thing - They would be in my neighborhood and wanted to sell me a walk in tub and/or shower. When I told her that I took all my showers at our local rec center, she was very polite and thanked me for my time.
