I called this number back this morning after getting dozens of calls from them over the last several weeks.
She was polite and I told her the number is on donotcall.gov list.
She said she'd notify the company about my 'do not call' number.
This company needs blitzed

to show them calls at all times of the day and night are unaceptable and especially when I am dealing with customers and the call is unwanted.
Ties up my answer service too.
Here's others called by them........
