Accidentally clicked merge with my erased data account HELP!

So I had the account erased issue where I dont have all of my characters or my skins and never got the account merge pop up earlier during launch until just now and accidently accepted it. will this erase whatever data they have of my old account from OW 1 in their database or will they have a backup? im freaking out because theres no way to cancel it and im still in the queue

I dont think so. But if it does contact blizz they will help u
