Razer Mamba Wireless - broken wireless receiver

Hi, I wonder if there's any chance of getting replacement receiver for my mamba mouse? I bought it 2 years ago from friend of a friend and today i kinda broke the receiver - it got stuck in usb socket and while trying to take it out I ended up with most of it in my hand but rest is still stuck in keyboard usb socket, it's now impossible to plug it in into any usb i could find and make it work. Is there any chance of buying somewhere a replacement or should i look for some 3rd party options?
