Ah-ah. I am sure even if you had millions of $ in support fees, they still won't care about you. You have to have pay more, get a dedicated accounts team and let them manage issues internally.

Google brought in around $284B in 2022, Big customers are at least double digits, so for Google, one needs to spend at least ~ 30B/yr to be considered a big customer to them.
