Razer Viper V2 Pro HyperSpeed Wireless Mouse

I bought one and it was terrific, a wonderful mouse to use. So I ordered a second. Took a while before I used the second one - it worked fine initially with a nice soft and flexible wire. But with use the wire started twisitng like old telephone coil cables used to twist. The wireless feature did not work - something must be wrong with the dongle or maybe the communications between mouse and dongle. After many interactions with customer service I learned a) a replacement dongle is not available for purchase b) there was something wrong with my initial setup of a Razer account or with my product registration. c) Ultimately I was informed that the purchase (from Amazon) was not through an authorized dealer so I should contact the dealer for support. d) The customer service is ridiculous. Each sappy email about understanding how you feel comes from a different name. Then you are asked to submit information that might take some of your time to respond, yet the next day or two another email arrives saying that they will close the case because they had not heard from you... e) Razer managed to take an enthusiastic buyer who bought two of these mice and would buy the new update, and was willing to purchase a part rather than look for warranty coverage, and turn him into someone who will likely never buy another Razer product ever,
