Anyone else have problems working with Microsoft's support contractor Mindtree Limited?

If someone from Microsoft is reading this, its a big problem that Mindtrees service personell managers are seriously spamming us customers after each closed ticket, its absurd and very annoying. I feel that the service persons that have had the ticket has tried to do what they can to help me, with varying results. 

However, what really bothers me is what it seems, they have a quite toxic feedback culture. The service people are extremely polite (to polite, because their managers are micro-gathering feedback on them), and after closing a ticket the person who helped me ask for feedback which I am happy to give in person.

Shortly after, their manager spam calls, multiple times , leaves voice messages, tries to contact multiple times on teams etc, because they want to gather feedback. I mean take the hint, if i don't reply, I don't want to give a feedback, do as any other normal company and send out a survery or something, and/or send out one, maximum two emails or similar. 

This is extremely annoying and has to stop.
