I tried to send some pennies to Cryptsy

First 2 transacions are deposited but rest of it like 4 x 900 m and 1 x 300 m and 1 x 1 didn`t deposited. Why ?
What to do now to recover it ? I checked it with small amount it was working then i send few 900m transactions and didnt come. After i tried again smaller and didnt come also
