I called it back, someone named Christina answered. I told her a missed a call from it and she asked how long ago. told her 15 minutes, then she asked for name or phone number, but didn't wait to get it.
She stated someone liked the job they did and got a certificate for us, she said it's for a free carpet or furniture cleaning. Told her i am not interested because we already use a service. She then tried to tell me they aren't a carpet company have i heard a vacuum called Curvy (sp?), told her i am not interested and she finally got the point.
don't give them any information, looks like they are just going down a call list.
