Mgs Cleaning Solutions

I purchased two Groupons for MGS to clean my eaves and windows. They booked the first apppointment, and pushed it back. They were great with communication - telling me why it was pushed back, etc. They then kept pushing appointments back until the Groupons were no longer valid (even though they said they would honour all Groupons since they were the ones rescheduling the appointment). However, after the Groupons expired, there was no more communication. No messages I have left have been answered, and they still have the money spent on the Groupons.
