This pool always cheat with user    for example if pool find a block from 400 to 420 then when we check out our transaction you can only see 9 or 11 blocks credit !  for example are as below

400
401
411
415

this what you can see in your transaction but in block tab you can see pool found a block from 400 to 420   where others block Coins goes ?? you won't see this problem every time but i have seen most of the time
