Forza Horizon 4 Support for achievements

Please give me the contact details of someone who can help me solve the problem with unlocking achievements. I keep getting referred from one department to another. From Playground to Xbox and then back to Playground. I received a very long email from Xbox in which it says that PLAYGROUND must solve my problem and this was written by a person from Xbox Support and despite the fact that I sent this email to Forza Support, I received ONE SENTENCE in response that I should write to Xbox… Please help because it’s been a dozen or so hours of conversations that have led nowhere. Support behaves as if it was AI working there and not people because they don’t respond to what I write at all. No one even bothers to sign their name and surname, my requests to forward the case to someone higher up are also ignored and this is a non-standard problem and these achievements must be unlocked manually. Please help. I’ve been buying your games since the X360 and I’m very disappointed with how you treat a loyal fan.
