Goodbye Razer: assistance does not exist

I use my Blackwidow Elite keyboard for work, but it has the volume key that doesn't work well. At the beginning of April, I contact them and they assure me that they can change it and to be even faster they make me cut the keyboard cable so I can no longer use it. Too bad that only after they let me do it and only after a week, they tell me that they don't have a similar keyboard to replace, so they will have to make a refund. They then ask me to wait 2 weeks (luckily that had to be a quick fix). No news. I contact them. No one answers. I have been waiting for a response from them for two months, I have asked several times but they no longer answer me. They have completely abandoned me, but in the meantime my keyboard is no longer usable. I had to buy a new keyboard (obviously not Razer), they still have my money and who knows if I will ever get a refund since no one answers anymore. No keyboard, no money, and no one answer. is this Razer assistance? I can only advise against this brand, or if you choose it, pray you don't need assistance. I just hope someone contacts me to solve this problem.
