My account is in trouble

Help, I just recently going to save my current grind. But, I clumsily pressed the download not the upload. I pressed the close quickly even it’s not finish downloading.
My stash is lost together with the items and can’t open including cystal and mythstone stash.
I was so excited because I received a message 1000x mythic color arena chest and it was lost also.
Here on my account just reach lvl 35 on battle arena. I was so sad and wanted to cry because I already got eternal mercenary, shadow, including some pet.
I wish it would repair my stashes and send again the 1000x mythic color arena chest. And restore some of my items.

Sorry dude
