There have been many similar cases where transactions do not appear either in the explorer or in the wallet, I will quote some responses to those transactions.

blockchain.info wallet not showing my balanceI guess their node is down... They show blocks up untill height 456544, while my node tells me the latest block has height 456561.
If their node is down, it's normal that your balance didn't decrease, since they don't have the block including your transaction... It might even be that they do not broadcast tx's... don't know how their setup is.
I think the same problem happened to you.

transaction not showing on blockchain.info (Block Explorer)
It was dropped by them and had a chain of another 2 transactions that were dropped as well. I pushed all three transactions back, you can now see it on blockchain.info as well.
Try blockcypher as an alternative.
Therefore, waiting, logging out, deleting cookies solves a lot of problems, but it's best to avoid using Wallet and Explorer.
