CHASE BANK ISSUED ME A CREDIT CARD THAN A YEAR LATER LINKED IT TO MY CHECKING ACCT. WITHOUT MY CONSENT AND SAY I VERBABALLY APPROVED IT ,BUT I DIDN'T

It sounds like you signed up for "auto-pay" so that your credit card bill would be paid each month from your checking account.  That would nt be done without some sort of written confirmation so check with your bank to see what document was submitted to the Bank from the credit card company.  Also check your emails as likely Chase emailed you to set this up. If there is an unauthorized debit from your checking account you can dispute that with your bank as well.
