Swan BTC instant buy help

I used the app for the first time and did instant purchase BTC. I accidentally did the wrong checking account ( I have 2 on there).

I know it usually takes 2 days to withdraw and sent a message to support asking them to take it out of my other checking account that i have on there.

I then deleted the info of the checking account that the purchase went through on. Being a weekend ill be lucky to hear from them on Monday if at all. Anyone know if it'll go through on the initial checking account or will it go through on my other and now only checking account listed. Thanks for any input....
