I bought the Marshall Major II Bluetooth headphones almost two years ago and they were doing well and I was happy with them. Now there's a problem with the controll knob on the backside. So I mailed the support service and got excellent help from them. I mailed some https aka ms remoteconnect photos and conformation that I really have bought them. Now they want me to totally destroy them by cutting cables and snapping them in half before they can send new ones. I find this quite an unusual procedure and want to know if this is normal and if anyone had made similar expierienced and if this is trustworthy.
