I got my PM'ed over the phone. A lot of it just depends on how you talk to the people, and some is the person you get. I tend to believe in the "get more flies with honey" approach, so I kill them with kindness and sweet talk my way into my PMs. I even tell them that I'm going to do the customer survey and/or that I'd like to leave them positive feedback with their supervisor, etc. Think about it, these people have kinda horrible jobs since they're mostly dealing with angry/displeased customers. As a person that has been in that situation, I remember that I was much more willing to help someone out who was kind to me than someone that was a jerk.
Anyhow, yep, got my $50 off, and actually I had previously already gotten this price matched when Amazon had it for $100, so I just got an extra $20 off because I didn't bother correcting them when they gave me the total refund. It was a slightly complicated process because I had also paid with RZ certificates, a gift card, and my BB credit card.
Thank you very much OP.
