After 15 emails over a month and a half, they still owe me for double charging me. They actually reversed the extra charge once and emailed me a record of the reversal, then turned around and re-billed me the same day.
They initially appeared to be very accommodating, answering my emails quickly. Their last email to me was two weeks ago. I replied that day and have received no more responses.
They also do business as www.losethesciaticpain.com.
