Sangeetha Mobiles — about cash back

Address:

Bangalore, Karnataka, 560037

I bought mobile from sangeeta store on marathalli. At the time of payment they told me if i pay through paytm, i will get casback of 500 and at that time they didn't told any condition. They told you will get casback in 24 to 48 hours. It's around 20 days and i didn't got my cash back. So i visited showroom and now they are telling that you won't get the cash back as mobile price is less than 8000, but at the time of payment they didn't told any condition. I bought mobile for my friend and now ultimate i lost 500 rs. Please do helpful. Its the worst service i experience from any shop. I also mailed to sangeeta mail id but i didn't got any reply.
