Greg, I feel your pain, in the end I found an MD for Google Pay, but by looking at her LinkedIn profile, she has moved on to another department, however she was extremely helpful in the end by having her team sort it.

You can try and reach out to her, because I am sure she will know the right people to put in touch with you.

Here is her LinkedIn profile:

I do hope you get it sorted. Success!
