DPI Energy DPI Teleconnect Paid Deposit to Start Service, Then Told I Don't Qualify and Can't Have Deposit Refund Until Next Month Carrollton, Texas

I tried to sign up for DPI Energy service. Pre-pay was explained and I was asked for a $50 deposit. I paid it via credit card on the phone. I was next sent to "Verification" where I was told I do not qualify for their service because I answered "Yes" to being a "critical care" customer (reliant on electric-powered medical equipment). I asked for my $50 back. I was repeatedly put on hold for 10-20 minutes at a time before being disconnected or picked back up by the same person acting like they hadn't just spoken with me before putting me on hold. I am told only that I can have my refund in 10-14 business days (two weeks and a day to three weeks from now), that they have no control over it because the main office does it, the main office doesn't take calls, and no one there even knows a number for the main office anyway. UTTER bull & I see now that they have a Better Business Bureau rating of "F".
