No way to contact support? Amended return and bank account details

Support is "too busy" or whatever, no matter how I try to contact. My amended return was submitted about an hour after my original 1040 the night before taxes were due. I had to pay the amount originally owed to avoid penalties, but the amendment showed I would actually be getting a refund both federal and state. The issue is, the amendment hasn't even shown up in the IRS system yet. No information or update, is this normal? Also, I got a notice in the mail stating my bank account details were not correct. So I tried to update them, there is no option to update them anywhere. My state refund came through already, this included the amended return. So I know both were submitted properly… I used the same information for everything.

Their payment pulled just fine from my account. I had accidentally scheduled two of the same payment, so one didn't go through and I got charged a 25$ fee for that. So all of their money is pulling just fine out of my account, but when it comes to it going into my account, it magically is not the correct banking information?

Summary because I ranted: 1. Amended 1040 return and it not being found anywhere on IRS or the tool to look it up.

1. My banking info unable to be updated but they claim its not correct despite all other transactions working properly
