Just had a PIP phone call which lasted about a minute and I’m confused.

So I just had an unexpected phone call from pip/dwp the conversation was literally security checks aka name,dob,postcode and then asked who I banked with and do I receive any benefits? Are those last two part of the security check or separate questions? She then proceeded to say in 7-10 days I’ll have my decision letter (this is the 2nd letter/1st appeal) she said if I disagree with it I can appeal a 2nd time…any help would be appreciated.
