My account was downgraded to a Basic plan, how can I reactivate my paid service?

Jay, I sincerely hope that Dropbox's response is to give this customer what I paid for: a usable Plus account for one year. So far, after 11 days, all I have received for my money (120 USD) is an account that was canceled on the second day, downgraded to Basic on the eighth day, with a minimum space of 2GB, to sync only 3 devices, with the money paid apparently lost, without the functional operation of my files (partially lost) on the 9th day. Not to mention the misinformation and lack of attention, not knowing what happened until now, the wasted time creating new email addresses in Gmail to be able to log back into the system and make the claim, losing files deleted because they no longer fit in a space reduced to 2GB, investigating the instances to whom to claim, and the worst: the annoyance of feeling the message from this company that the customer's satisfaction, time, files, and money are the least important! Honestly, for me, it is an absurd, unprecedented, and surreal situation. Being used to buying licenses, software, online services, IT products, this is the first time I have experienced something like this. Anyway, the good thing is that I don't give up easily. I want to receive what I paid for. What's wrong with that? Am I wrong? This is what we customers want. What's going on with this provider, Dropbox?
