No one helping with amendment

I had opted for full service and after my taxes were filed, I found some issues.  My RSU ownership was not declared in form 8938 and I tried to reach back for help with amendment. When I purchase full service, Turbotax bragged about how awesome they are with  helping amendment, audit etc. Now, here we are! First I was assigned a person who stopped responding, then a new person who only work for few hours on week day and cannot talk to me on phone. I tried to call the customer service and spoke with someone and explained my issue, they just dropped my call. Not sure why the service has gotten so terrible. Looks like I need to find someone outside Turbotax to work with moving forward
