In-App Purchase Errors, charged $3.99 but never got score!

Sorry, but I have to give this App 1 star - I tried to buy a score twice and got errors both times. No sheet delivered to my device, yet I was charged $3.99!! Avid Customer Support completely unresponsive. I had to contact Apple Support for some resolution. If that fails, I will dispute with my CC company. No way am I giving away $3.99 for nothing, just on principle. Avid, please QC your app and step up CS.
