I found GV911 to have excellent customer service. I had a typo so accidentally created two GV911 accounts. My payment of $12 was credited to the account with a typo. I emailed them- not understanding why I could not see the money in the account. They replied at start of business. We had to go back and forth twice (they always replied within minutes), and they moved the money into the correct account and cancelled the one with a typo.
Just a heads up- I found that I had to use these instructions on the Obitalk site to finish provisioning the E911 service:
