Dear sir.
I'm Nazim from tumkur. Karnataka.
I'm purchased reflex smart band on March 09 2021 now band is working good but my band belts was cut. I went Fastrack showroom for replacing the belts but Fastrack exicutive say it can't be replace kindly replace your band or purchase another one... It's Fastrack don't provide band belts means how we thought out our working band it's cost of 2200rs when I purchased. Nw they asking it's no use...
I'm waiting for your response.
Kindly give me your valuable time
Thank you
