I’m a little late to this party but I had something similar happen to me it was the New Zealand post version of it… I would’ve kept going too (so dumb I know) and it was legit right up until I told them I wasn’t with any of the major banks that I was with a credit union and the supposed NZ Post live chat replied to me and I quote “then you better get the “duck” outta here. Thank God for my humble little credit union account 😂
