It mostly happen when the fees are very very low or no fee applied in the transaction.
How long have you waiting since you made the transaction?
Also for information the amount of bitcoin will be sent back to the sender
Hi, thanks for your reply, Im Piiko.com Official, Someone tried to Topup his number Using our site, and Sent the Payment but that was Pruned by blockchain, May be because of Low fees as you mentioned. I dont know when he sent that payment, and I dont know weather he got any Message. He Sent me First PM on 13 and Second 19 that he still not got paid.
I think some information are missing here,
If he has sent 0.01351228 btc then he should get it back after few days (mostly 2-3 days) after he tried to send the bitcoins to you.
The blockchain does not show when the returned balance arrived to the address as it was not included in any block. It is counted as no transaction was made.
