HAS ANYONE HAD NUMBER PAD DOUBLE KEY A NUMBER ON A V4 KEYBOARD?

keyboard bought direct from Razer store 7/18  so only 3 ½ months or so time on this board. This was a replacement for Ducky Shine 7, which was really flawless and will have to go back in service. I contacted Support for help or and RMA, My question was, could the switch be replaced without soldering. Rather get an answer They want proof of purchase  and their order number and I have already supplied a Serial, so I emailed them their own invoice back, now they are Ghosting me. Is this common for support to ignore a paying customer with a warranty problem. I am not a 16yr old gamer, I do engineering  work daily on this keyboard, and 2 5’s entered by defect could cause an engineering failure in my line of work. If I was to  rate Razer equipment quality and now support on a scale of 1to 10 that would be a 2 and I would differently not recommend buying their equipment now! I have  probably bought 6 to 10 mice and a ITX case from Razer over the years, and I can say every mouse I have bought other than the current one I use with my laptop have all failed and I bought one of the first high DPI mouse that Razer marketed. If I do not some action of either a repair or return on this keyboard my future comments will be out on every forum and Podcast  reviewer I feel will listen to the support/ quality issue.
