Everything engineering runs through the public repository, so an answer helps the next person too. Please never include passwords, keys, phone numbers of real payers, or payment data in an issue.
Questions and bugs
Open an issue: say what you expected, what happened, and what the engine said. Wrong-looking money matters get looked at first.
Security reports
Vulnerabilities do not belong in a public issue. Report them privately; the security policy says what is in scope and how reports are handled.
If you paid a business
Start with the business you paid: they hold the payment's reference and their provider relationship. This service's operator can trace a payment from a reference or the number you paid from, and the privacy page explains what is stored.
Partners and providers
Onboarding a business, or connecting a provider, starts from ifinsta.com, which owns the businesses and the partner credentials. The provider protocol document explains what a connector must provide before it ships.
