Doubt. We're paying ~$10k/month on ads. The Ads API is rate limited, but it's either broken or has arcane logic, so about every 4-6 weeks, the usual workload will trigger it and we're shut out for 12-24 hours. Can talk to ad support whenever I want, but all they are good for is optimizing campaigns and explaining the UI. No option to get to technical support, no option for ads support to escalate.
Of course, we might not be a large enough customer, but it certainly isn't about "paying".
