I need to integrate with service A. There is an issue.

Me: Service A, we have an issue. We don't get any errors but the final entity doesn't get created
ServiceA: Ahh, I see. Since you didn't get any errors, try escalating this to Service B - we are using it and they might see what's wrong.
Ticket: *closed*

Me: Service B, we have an issue and ServiceA says I should talk to you.
ServiceB: Ahh, I see. I don't see any errors in our logs. Try escalating this to Service C
Ticket: *closed*

Me: Service C, we have an issue and Service B says I should talk to you.
ServiceC: How do you send the request to us?
Me: I don't. Service B does.
ServiceC: I see. I don't see any requests coming from them. Talk to Service B
Ticket: *closed*

Me: Service B, Service C says you don't send a request. Please have a look.

Each ticket takes 2-3 days to be noticed.
