Tax Expert Ditched Me

I was working with a tax expert for hours yesterday.  She seemed unfamiliar with my tax situations and told me she need to speak with her supervisor and that she would send me a message the next day in the afternoon to speak again.  Didn't hear from her until almost 7pm...it said she had sent me a message.  6 minutes later I received another message saying that my Full Service experience has been closed.  I cannot view the message or contact her.  What is going on?  Is this a common experience?  Feels like a huge waste of time and I will I be  charged for this non service?
