Rain wifi - no service coverage and charged twice for no service

I ordered a Rain wifi package for my home telephonically. The Rain consultant assured me I that Rain does have coverage in my residential area. The Rain sim card arrived and did not work after being activated on Rain's system. After many phone calls to their support they could not find a solution as to why it would not work and the refused to send a technician to assist. I requested a refund and processed a cancellation as the sim card never worked and I was not able to use the service at all. The Rain consultant confirmed my refund was being processed and should take a few days, I followed up a few days later and was told the same. When I checked today I see they never refunded me and instead they deducted another month's fee. So I paid for 2 months' service and received no service!
