Terrible Customer Service

Once again am dealt with some of the worst customer support that I have ever experienced. I sent in my Razer Nari over a month ago because of an issue with the mic. I then had to wait 16 days just top receive the Razer Nari Essential. This is not the headset that I sent into get a replacement of and has a $50 dollar difference in MSRP. So I called the support line and got told that they sent the Razer Nari Essential because they didn't have any more of the Razer Nari in stock at the time. I was then given a FEDEX label to return the Razer Nari Essential so they could send me the correct item, the Razer Nari. I have waited 14 days to receive the Razer Nari and I just got the replacement today and once again I received the Razer Nari Essential, which is NOT the product I sent in. This is just completely unacceptable and I really have no clue how this company and support service can mess up twice over the same exact issue. I have tried to stay patient throughout this process but I don't know what I am supposed to do at this point because I feel like I'll never get the product I was supposed to receive.
