Anyone with Chase banking has issues with name updating?

I have an unenrolled deed poll, have updated my name on all banking, my mortgage, passport etc. but for some reason chase are adamant that i need an enrolled poll (even though their website says a passport is suffice)

In chat this is the conversation i’ve had: “For documentation, would it be okay if you can also share as to why you only have the unenrolled deed poll?”

my response was “i’ve not needed an enrolled deed poll as my ID had been updated “Enrolling a deed poll has no legal benefits and is not required by any government organisations for officially changing your name.” (UK deed poll office)””

I don’t see why there’s so much hassle with the name update. But i’ve had everything else changed since the end of september and i’m not sure why this is so difficult :,)
