I even thought that the bitcoin from that transactions will be returned.

Well thanks to those miners maybe they also included this transaction upon seeing that it is now taking sometime.

Just learn the lesson from this incident.

Upon looking at your TXID.

Everything is fine now, you've got 6 confirmations you will receive your bitcoins good for now.

Next time, try to settle a good miners fee.

I am surprised that Blockchain.info still lets anyone do this in the first place, because nowadays zero-fee transactions are mostly likely to be ignored/rejected by all miners. Furthermore, I don't think that the Blockchain.info wallet lets you increase the fees of an already broadcast tx.

However, there are "external" options to expedite or salvage zero-fee transactions, for example this one from BTC.com mining pool

PS: your post is likely to be moved to service discussion by a moderator, so I'd suggest you to do it yourself

EDIT: oops, I just realised that payment at the accelerator link that I provided seems only available to Chinese bank card holders... there might be other such services available though.
