There is no other way to say this, but RegisterFly is the quintessential scum of this earth. They have stolen domains from me, among other things. However, even when I talk to their damn management (Mr. Glenn Stansbury via telephone), he promised a full refund in 3 days. 3 months later; no refund.
The first registrar that I will EVER give a zero rating to is RegisterFly.
I rate them -10/10.
