Pd $29- expert final review. Expert called-dropped midway. No call back. cust service can't find expert- suggested a refund thru a link. Refund rejected. How to handle?

$29 is for an expert final review, as suggested by Turbo Tax. The expert didn't reach closure. call got dropped and no call back. no way to reach the expert back. Feel like I paid $29 for nothing. Customer service wasn't helpful to reach the same expert or another. and they suggested the refund and even said the refund would be approved. Then the refund is rejected - with no way to follow up. Very bad customer service for sure. How to handle this?
