You can aim to dispute the charges.
RamaWorks delivery time frame can only be described as "when it's done." It's up to them to decide when they are done QC'ing the board. It's the "GB experience" for the lack of better term. As with any other group buys (GB) for some reason, long waiting times and delays have to be expected. Understandably, they should be not over-promising the time it takes to make and QC the boards. But, here we are: ETA listed is almost always just an extremely optimistic time frame.
Speaking of, RAMA U80-A SEQ2 delivers about 1+ year. They are not scammers per se, but they are notorious for not fulfilling the listed time frame. So much so that I'd add an additional year to their listed time and it would probably come as "expected."
TL;DR: dispute immediately if you wish, especially with PayPal because they have the time frame; remember that if you use credit card for such purchases, you can convince RamaWorks to "hurry the fuck up" even though it has passed the deadline. They deliver and the boards are good... but that does not excuse the ETA that is starting to seem habitually deceptive at this point.

!I was going to go on a tangent on the other company that needs you to wait at least 2+ years to get 160+ plastic keycaps... But let's just say it's a low hanging fruit and I am not "proud" to have the "patience" to wait for that long.!<
Sorry to say but welcome to the Rama experience. People who have been in the hobby for a bit have seen Rama nosedive completely and setting their unhinged ranting about some ex-“colleague” drama aside they’ve been missing their deadlines consistently for well over a year. I would stay far far away from them, issue chargebacks ASAP if applicable, and never look back. >

I would have been quite interested to see where they took the double-shot poly carbonate and pbt/abs mix.
It had potential at least. Just they caps never seem to have actually gone out… Good ideas, boutique pricing, dollar store support. >

I am so sorry you are dealing with this. I would be very upset if this was me going through this.
There's an Instagram account with 78.3K followers, @ramaworks
There's a Twitter account, too.
Allegedly two key people left and formed another company.
My advice: contact them through Instagram and if no response in 48 hours, dispute the $600 charge with whatever form of payment you used originally, and find another build for your bro.
Good luck. >

They don’t respond to DMs, and disputing may be too late as it has been almost 2 years. 
There are interesting rumours that Rama is broke now and they’re selling non-keyboard stuff like pens and collectibles to fund past GBs rofl >

Man’s gotta sell his mclaren >

There was an in-depth post on them on sub awhile back. I’ve linked it here. Hopefully this helps clarify things. >

They delivered all my boards, two u80 seq2, a kara and a m60-A tank. All took more than a year and a half except when in stock. "Rama works" is kinda "Rama works slow". Sorry man >

Happy Cake Day! :))) >

It's unfortunate because when they do deliver it's quality stuff. I love my U80-A. I bought their wilba-less U80-A PCB because flex cuts but I'm not expecting it to arrive any time soon. 
Seems to be a thing in this hobby-- even previously reliable vendors can ghost you cough mouser cough >

Delays happen and usually releases on group buys are an estimate. Expecting December 2022 but getting it about a month later is pretty par for the course. 
With that said, that is not an excuse for poor customer service especially when these are not ‘cheap’ purchases. These are expensive items. Personally, I had a few issues with my Thermal PCB and they were quick to respond and addressed the issue. However, this was their first release and I think there has been some organizational changes with a partner, who was supposedly responsible for a lot of the designs, leaving and forming Hibi.mx.
Welcome to the hobby and I hope your friend enjoys their Thermal. It is still a pretty nice board. >

I have to say that I bought a rama keycap and it was so terrible and ill fitting that I realized they were all hype. I was able to return it and I never bought anything else from them.
