Barclays PLC Bank Account Or Service Complaint

Barclays PLC Bank account or service department,

Savings account Account opening, closing, or management Georgia

I have submitted several request to Barclays bank as to whether they are FDIC insured or not and up to what amount. They continue to give me the run around and to send me an invalid link to check to see if they are FDIC insured. I do not understand if they are a full regulated bank whey they do not know themselves if they are insured or not?
