How can I contact live support? I paid the last missing payment, but I have no files or storage. Everything is gone. So frustrated.

Very frustrated. I didnt realize I had lapsed on an older domain that I used. I went to access my Google Sheets, saw the last payment had gone through. Figured the files were worth it. I paid the $200 I owed, then found I had no storage, no files, and nothing there. So I essentially gave $200 to Google for no reason. I need to talk to an agent and either get my files back, or get a refund. It's ridiculous how difficult it is to even talk to a live agent via chat. Very, very frustrated with Google Support and not sure what to do now.
