After you file

I have not received my DocuSign documents from my tax expert.  It has been since 3/05/2020 that I have been done with my taxes. My tax preparation "expert " has Not responded to my emails.  I am Extremely Upset about this.  I payed for this service and have not had a good experience at all. I have tried calling the number suggested and it keeps saying they are not available,  even though the message said they are available from 5am till 7pm Monday through Friday.  I can Not seem to get any answers!!!!
