Sensor Broken

Hi Guys, I have been using the Glorious Modell O Glossy Black for acouple of months now and really enjoy using it .I unfortounately droped it yesterday and now the sensor has stoped working correctly (I think) for example when i move the mouse around the dpi will randomly change .Another strange change is that when i use my mouse Pad (Big Office one) the mouse DPI Starts dropping massivly .

Any advice on how to fix this problem would be greatly appreciated, Thanks in Advance !!
