I bought prestige toaster pptsks worth rs.1310 online. Its been not even a week of my purchase, my pop-up toaster stopped working. The bread toasts are popping up before being toasted at all. I was told to be provided with an exchange of a new one after emailing customer care. But after few responses, they are nor emailing anymore nor taking any action. I visited the service center nearby my house, they initially fixed it. After returning home, i found it the same defective. Please resolve my problem asap. I have spent money with a trust on your website and online shopping. Now i am totally disappointed, harassed and helpless. I paid my money and in return i got a defective product which does not work for even one week. I am writing you with immense hope. Please exchange the defective product for a new one.
