Hello,
2 days ago I received BTC0.002
It was pending from 2 days.
But today I can not find that btc not pending nor added
what's wrong?
The only thing it can happen is if the received transaction has got very little transaction fees then it got rejected after some time and the bitcoins will be sent back to the sent wallet address. So you can get details from the person who sent you the bitcoins. Other then that if you need help then you have to provide some more details about the transaction.
