I don't normally put too much thought into making note of Customer Service interactions if they go alright, but I have one for PIA. (I work in Customer Support, so I appreciate this even more!)
I created a ticket last night (Saturday at about midnight, PDT) and I got a reply back this morning at 4:30 AM. I had renewed a subscription on an old account so I wanted to get a refund. They offered me two options, one was a refund and another was to merge my two account's 3 year sub into 6 years. At 11:20, I opted for the refund and within 4 minutes they said they they would process my refund. 5 minutes later after my email (11:25) I got an email from Paypal that my $79 was refunded and is available to spend on the 17th of April.
Fantastic response time, plus its on a weekend, and the resolution is exactly what I wanted. I should note that my mistake purchase occurred only a few days ago, which is well within their 30 day refund.
I have to give credit when credit is due... Great job PIA! (I can post screenshots if anyone cares )
