The product delieverd to me is fake and is instead a cheap material worth only 50 rupees... It is making a weird noise but they claimed the device produces ultrasonic sound which is inaudible to human ears
The number which was provided in the message was also fake as when i made a call on that number it was automatically got cut after a few rings, i tried calling a bunch of times but there was no answe at all
I want my money back it cost me ₹480 and is certainly not cheap that i can just ignore it
