guitarpartssite.com Took money, delayed shipment, denied refund, told me to dispute it Internet, Internet

I purchased a guitar part (Ibanez 2FA1C10LC FAT10 TREM SET/CHROME) from this website as in stock and received an email that my order was in progress. I additionally received the ability to log into the site and check on my order.  After a few weeks, I returned to check on the status of my order which was still awaiting shipping. After 4 weeks my order went into the following status:

NOTE: This order has already shipped or has reached the final stages of processing. Therefore this order is no longer editable.

At this point I sent an email to the site asking the status. Two more weeks passed with no response. Finally I called and spoke to a representative. He agreed that it had been a long time and the parts should have shipped but could offer me no eta on when it would ever ship as it was a remote warehouse. I asked to have a refund submitted, he agreed and said he would process it. Four more weeks pass and I realize I never received a refund. I again email and place a call to find out the status. At this point the representative tells me that it must no be available anymore. I again ask for a refund and this time he says that he cant do that and that I should dispute the charges.

Since this was with Paypal, by this time the time frame had run out that a charge can be disputed.

I have repeatedly emailed them to get resolution but have repeatedly been ignored.
