I too have had numerous calls from a walk in tub company, but I am not sure that this is their number. Someone just called from this number and did not leave a message, but I would certainly check to see if this number is being used by the Walk In Bathtub Co. I am on the do not call list as well and should not be getting repeated calls by any solicitor.
I get calls from this number at least once a day.Pick up, no one there. I blocked them, but my phone still rings once on a blocked caller. Call them back and the number is out of service.
