Should I cut ties with PSA and just ask for my money and cards back?

[packs]

I submitted the following 2 cards to PSA in person while they were in San Francisco on April 14th. I paid for the minimum service and encapsulation. The shipping service I paid for was for 20 business days. Today is the 25th business day and my order is still "in process." When I asked customer service why my order was still in process this late in my service timetable they didn't really have an answer. I purchased both of these cards from Board members and have no reason at all the suspect they aren't authentic. I know my turn around time is an estimate, but they can't tell when I can expect my cards back.

Would you ask for your money and encapsulation fees back and just eat the shipping cost or do you think I should wait it out? I'm worried that at this point I've pissed them off with my complaints and they'll just say the signatures are no good and send them back to me.
