Recertification Fail Massive Payment

I got the notice that I needed to recertify this year. I was on the PAYE plan. I submitted my tax return as verification and answered all of the questions. Yesterday, I got an email that they rejected my recertification method and this morning an email from Mohela that I didn’t recertify and I will now have a standard payment plan and my payment will be over $2k. It also updated my automatic withdrawal for this massive amount.

Please help
