Amended return says completed and sent but I still haven’t received

I Amended my 2020 return on April 20, and on July 30 using the IRS tool it said that it was adjusted, then on August 20 it said that a letter should’ve been sent to me and then it resulted in a refund and was completed. Now it’s September 9 and I still haven’t received a refund and whenever I called the IRS they said my account was still open and that it hasn’t even been adjusted yet. The reason that I amended my return was because when we got the unemployment tax break it qualified me for the earned income credit and the additional child tax credit which was going to be an extra $2643. I received $658 direct deposit which I’m guessing is for the taxes I over paid. They said they don’t send out amended returns direct deposit so that shouldn’t have been the amended return. So have y’all ever ran into this problem with the IRS saying that they amended a return and that it was completed but when you call it shows that nothing has been done at all and that there isnt anybody I can talk to about why it says that?
