M120 Wireless mouse , sensor issues

[AyanM10]

I bought M120 Wireless mouse from Amazon, but after using it for a month, I started facing sensore issues where the sensor started moving without even moving the mouse. I cleaned the sensors, but still faced the problem. While this problem was there, the battery used for the mouse started draining fast. I had to change the batteries in just two days. So to claim the warranty, I registered the product, but it didn't seem to work, whenever I wanted to add the product, it showed "Please enter a valid Serial Number" even though I added the same serial number as on the Bar Code of the box....Please help me claim the warranty.
