Still waiting for refund for unnecessary duplicate charges from Turbo Tax

I'd like to think Turbo Tax is interested in ensuring customer satisfaction, but instead I've been mostly ignored the past hour in an attempt to have TT remedy a billing "error"

I wrote to TT to ask for the umpteenth time why I hadn't received payment from TT for $153.90. That's what TT overcharged me when I filed my return mid April.  I had already purchased TT from Costco. I've filed the same way for  many years  purchasing TT from Costco and then filing through TT's website.  Never had this problem before. Was never asked to pay TT directly when filing.  That was automatically included in the purchase price. Don't think anyone is  interested in spending a few hours entering info to complete a tax form and then not filing same. 

Now I'm once again wasting my time. I can only assume TT does this on a regular basis and simply wants to cheat its customers.  I did enter a dispute spending much time on line with TT's reps when I filed my return mid-April.  But never heard back nor did I receive a refund for the amount indicated above, although this was promised.

Should I assume TT does this as a means to increase its revenue stream?  Would TT like to reimburse me for the time I've spent trying to reach them and right after filing taxes in an attempt to have this taken care of?

Gee... should I use TT next year considering its total lack of concern for a legitimate question to an inexusable problem created by TT?

Look forward to TT's reply!!!!
