False promises made by Quality Contractors Builders Inc. representative

I'm writing to complain about the return process I received from Quality Contractors Builders Inc.. After paying $399.81 for device, I found that it doesn't work as advertised. I've tried resolving this with your customer service team multiple times, including speaking with Ahmed C., but have not received a satisfactory resolution.
