Thanks for the replies. Just an update - I finally got my pad yesterday, exactly 3 months from order date.
I ended up getting SeaDek involved and calling Jim's cell number. Ended up having to place my order directly with SeaDek. Due to the issues, they actually took care of me pretty well with 20% off the order and free shipping. Ended up being about $75 cheaper than my order with Jim.
As for Jim, I finally got him to answer his cell and we had a lengthy conversation about the lack of customer service and communication. He admitted to those faults and ended up refunding me double what I paid him for the lack of service I had from him and the messed up order.
All in all, financially it worked out nicely, but the 3 month wait time and the frustration of calling Jim multiple times daily for a month was driving me nuts.
