Missing contact info, autommations not working, bad support

I´ve been having a lot of issues in AC, I recently hired the service and it has gone downhill fast.

First: My autommations are not working, they do not suscribe to the lists I programmed them to, they don´t gather the information from Meta Forms and now even the information is missing in the contact itself, even tho I have everything the same, it literally changed the next day everything is a dissaster.

Second: I have asked for help to support and never have they helped me, I have fixed everything myself until this point were there is nothing I can do.

Does the AC system has been presenting general issues or has the assist to beginners just does not teach good?
