Had a transaction stuck:
https://blockchain.info/tx/5ebd2a1843097cba44b81b0bccdf7efa48c8b0ee1fff0b121d4c3f6d3171564b

communicated via Telegram, got an address where to pay, and after payment within 25 minutes my transaction was confirmed.

Especially recommended in case you're stuck and post-mortem advice to put a larger fee is.... well... as good as any post-mortem advice ))
 Agree with the guy above me - totally worth the 7$

Noe to owner: you guys should update the website ASAP! alipay no longer works... (turns out that site isn't operated by the owner, but merely provided as a reference for price estimate)

Thanks
