K in N

I bought a voucher off of Dealfind in late summer for apparently a $135.00 service. I set up the appointment and they proceeded to claim that they couldn't find my home - once I contacted them to find out why they didn't show. The rescheduled, unable to come due to the weather. I had an email saying they'd reschedule in the spring. They have booked me an appointment but told me I now have to leave my voucher and $6 under my door mat. I questioned why this had changed as it wasn't a requirement previously, and asking what exactly they plan to do for service as it's no longer a fall service. I haven't heard back and they have their phone set up to not receive voicemails. I am not hapy and expect that I won't see them at all based on the other rooms. Disgusting example of customer service. It's really a shame because if they were any good I would have hired them for my painting needs too.
