Universal credit compliance telephone interview

I have been on u since Oct 2025. Migrated from esa support group with income related in benefit. Cut the story short. I was overpaid u. I am getting new style esa also with uc. Uc had not taken my esa off my benefit from end of January and February on my statement. I went to job centre and informed them. I opened a savings account so I did spend the £600 overpayment. I informed uc regarding the new account. Got a repayment letter and paid it straight away. Next thing I known I have a message to phone them. It's tell me I have a compliance telephone interview. They have asked for 2 mouth bank statements January and February. When I spoke to the compliance guy who going to the phone interview. He didn't tell me much wait till the interview. But afer I spoke to him I had to phone uc. They wanted to inform of the same as before the bank statements. So worried regards this. Has anyone else been though this. Regards thank you
