Li-ion, my name is Ben Schaffer and I'm the co-founder of Unplugged Performance. Thankfully I got a text message from a friend of mine at 9am (an hour ago) which pointed me to this thread and I've logged into our company account to directly reply.
Firstly, I want to apologize that somehow we've either missed your refund request or dropped the ball. Whatever the case may be, it is not intentional and we absolutely refund anyone in such a case that they no longer wish to wait for a backordered item. A private message was sent to you with my direct email address and I hope you'll email me so that I can personally oversee expediting your refund today.
20 years ago I founded Bulletproof Automotive (which has enjoyed an unusually rare 20 year existence in the aftermarket), and in 2013 we set out on a new path and started Unplugged Performance after a friendly chat with our Hawthorne business park neighbors at Tesla. In the 20 years I've conducted business, I've never been accused of scamming anyone, nor have I ever. Rest assured we will resolve this ASAP. Our company's history is easy to look up, as it my personal history in the industry. We've been around for 20 years because of our ethics and our unyielding commitment towards creating projects and custom work that our customers love.
Where we have clearly failed is by missing your email requests and therefore not acting swiftly enough to provide a refund. I'll be personally overseeing this and also reviewing how we may have failed to see or respond to your emails in a timely manner. Once again, my apologies for the trouble caused and we will get this resolved ASAP for you.
