Complaint Review: Coinbase

I sold some Bitcoin on 3/9/21 and to date today 4/17/21 they have not put the money into my bank account.  I have filled out the information they have on their complaint form 3 different times and no response or received my money into my account at my bank which they have all the information.  It's the same account I have used to buy various crypto on many times over the years.  

I need a legal firm to contact myself and others experiencing this rip off!  Now that they are a public company I would think the SEC would act on this!  There is no one to talk to or corespond with at Coinbase!
