I'm done. Never will I ever deal with Amazon again. Full story here:
I order a pair of 1770 from Amazon directly for 400$ (using a 20% promo code). It says out of stock, but I'm optimistic (a month till Christmas).
A couple of days later I contact Amazon support, asking when the item will be available. Agent says something has gone wrong, and that I should reorder from their 3rd party vendor. The 1770 costs 600$ from their 3rd party vendor, so I ask the agent about the price difference. No problems I'm told, I shall just order the item for 600$ and contact Amazon when the money has been transfered. They will issue a 200$ refund, so my effective payment is 400$ (the original price). Cool.
About a week later I contact Amazon again, and ask about the 200$ refund. No problem they say, and issue a refund.
A couple days later, I check my bank account, and sure enough, there's a refund. But it's only 150$. I contact Amazon about it. The agent replies that there must've been a mistake, and says he's taken care of it.
It's now Christmas, and I finally get to try the headphones (present from my parents). They're magnificent! Just what I wanted. Same afternoon I hear a weird buzzing noise. I ran them straight out of my jack in my laptop, so I figure that is the cause. I also still haven't received the remaining 50$ from Amazon, so I contact them again. It is now the 25th (we celebrate Christmas the 24th in Denmark). They refuse to pay the refund, but offer a promotional offer of 50$ instead. I don't accept this, as I just want the money back, but they cannot do this apparently, since I used a 20% off promo code (which is the remaining 50$? Your math doesn't check out Amazon). I escalate it all the way to the top, and finally, after close to 4 hours, they disconnect on me.
A couple of days later, I contact them again. I get the exact same lines copy/pasted. "System doesn't allow for the refund of the remaining 50$, but I can give you a promotional offer of 50$". "I will not be able to offer any more insight into this case. Is there anything else I can help you with?". After 2 hours of this, I finally disconnect, still unhappy.
A day later, it's not the 28th or 29th. I realize my headphones are broken. The right driver is rattling. Many people reporting exactly the same problems. Okay, so I'll just get a replacement?
It's now the 31th, 3 AM. I've been talking to Amazon support for about an hour now. They cannot offer me a replacement, since I ordered from a 3rd party vendor (I originally ordered from Amazon directly, but due to the re-order I had to order from a 3rd party vendor). As such, I cannot get a replacement, but I can get a refund. They're offering a refund of 450$. Okay then, but a new pair costs 600$? Can I get a discount if I order a new pair of headphones? Nope. Not at all. No chance in hell. So what do I do now? I paid 450$ for my headphones, and I cannot get a replacement. I can get a refund of 450$, but that isn't enough to buy a new pair?
If I return the headphones to Amazon, I get a net loss of 0$, but I've wasted 12-15 hours fighting their customer support. Furthermore, I've used favors to get the headphones from the US to Denmark. All for nothing.
I will contact him, I don't want to send the broken tube back though, what will he do with it?
Looks like my 79 GBP are coming back soon, meaning, more EL3N tubes haha
