Razer refusing to refund me for returned laptop and lied to Paypal about recieving it

So on December 4 2018 I decided I wanted to buy the new Razer Blade Stealth 2019. The new mx150 seemed like a good balance of power in a portable package. After it arrives on December 13 2018 I discover that my unit had noticable coilwhine when under load. I give the laptop week to see if it would be a problem and determined December 20 2018 that I didn't want to keep the unit and wanted to return it within my 15 day return window.

I get an RMA from razer and am told to send my laptop to: Razer KULS, LLC. Doors 1-6 24760 S. Main St. Carson, CA 90745 I take it to my local Fedex and pay for the shipping back as Razer did not provide me with one and did not specify that I would be getting one.

Now December 25 2019 I get another email from Razer with a shipping label saying to send my laptop to: Razer USA 9 Pasteur Suite 100 Irvine, CA 92618 Carson, CA 90745 At this point I'm panicking because this is a different address than what I was given and when I email them back saying I got two emails with different addresses I never get a response.

December 28 2018 rolls around and I get a confirmation from Fedex that my package arrived and was signed by someone named Ricardo. And now I finally get a response back from Razer saying they got the laptop and that it will take 2-3 days to issue the refund and it can take 10-15 days for it to post on my paypal account.

So January 13 2019 comes around and I have yet to hear back from Razer and decide to email them as my return was do. January 15 2019 comes around and they tell me they are working hard to issue my refund and my time is precious to them. Please allow 2-3 days. Well three more days go by and I hear nothing.

So at this point I file a dispute with Paypal saying I did not get my refund. I provide them with a picture of my return receipt with fedex. I figure they will help get my refund. Last night January 29 2019. I get a notification from paypal that my request has been denied. The website had no information as to why so I call Paypal to get an answer. The representative that I got reviewed my case and confirmed they got my tracking number and told me this "Razer has claimed they did not recieve the laptop and that your tracking number is invalid" "They also say there is NO RAZER RETURN CENTER IN THE USA." I tell them I have an email from Razer telling me to send it to that location. So paypal says they will reopen my case and I can send them the email in 72 hrs when the case is reopened.

So as of right now I returned the laptop, have not recieved the refund, was denied a refund from Paypal because Razer claims they don't have it or the address they gave me even exists. So I'm at a lose at what to do. I'm not a youtuber so I can't make a video that will reach the eyes of millions and make Razer realize they messed up. So what can I do? Razer seems to be trying everything to make me pay for a laptop that they signed for as returned.

Thoughts or advice?
