So far, I have no complaints about the service. I did have a couple of fails on some of the first accounts I tested, but once I applied the OP recommendations that he sent me via Skype (quite prompt reply, just a couple of hours after I asked him), I have had only a couple of fails.
Taking into consideration the low cost of the service, and the very few problems I know encounter, I´d say that this is a good phone verification service. I don´t mean to sound disrespectful to any of my BH colleagues who have posted complaints on the thread, but seriously, why do everyone get so fucking mad and nervous when dealing with this kind of things??? The OP clearly states that the PayPal charge may take a couple of hours, and so far he is always willing to assist and detail the best procedures, so before trashing your own personal shit on this thread you first should try to ask him personally via Skype.
