Yeah, you want to "take this offline" and handle OP's case individually, and perhaps OP gets their demands met, some sort of service credit, or something.
But what the rest of us want is real systemic change, to where managed services like this actually give us real value, and not "marginal value, but nothing works like it ought to and you're going to spend a lot of time working around the bugs and gluing the parts together", where every bug report (which has to be filed as a support ticket) is met with "you're holding it wrong", or where the service goes down and the status page gaslights us, or …
Buying managed services instead of letting engineers do their jobs is today's "nobody got fired for buying IBM".
