Those Balckhat method of pva now a days no longer works.. cause you need to do re-verification in few days or after few post.. so you need same number once again.. suggesting to buy from a good pva seller.. never buy all a time. First buy few like 4-5 to test how they works.. after getting experience and quality of pva, you can buy more, better not to get scammed.
and if you are very new to CL or pva, suggesting to use any posting service for you.
thanks
