Exhanged 9.4 BTG to Bitcoin Exchange Failed on Coinomi Changelly

Hi I exchanged 9.4 Bitcoin Gold to Bitcoin through Changelly on the Coinomi Wallet on MONDAY 8th January 11:48 AM. The exchange has had over 300
confirmations but has came back as FAILED.

My Bitcoin Gold has not been received back that was over £1600 GBP missing from my coinomi wallet account I have attached screenshots of the failed transaction and emailed Changelly with screenshots and the Transaction ID also emailed Coinomi. Coinomi have replied to say contact changelly as its their responsibility no reply yet from changelly.

I suspect changelly is just a scam. Anything I can do to try and get my funds back ?

The Transaction ID IS 713d3a9b25a0b108d3e51a5e7b7f2faf78bd8ac0c4aaa039d6dedbdddc1c1746

Which can be viewed on the block chain explorer BTGexp.com

Any help with recovering funds would be great guys cant let changelly.com away with this.
