I have ordered a plano zero power glass on january 11th with the prepaid option and paid it through paytm wallet, but my delivered was not done as they said me that they approached my address and found none, but in actual i have not received any calls or message regarding the delivery, then i was promised that i will get my refund as i have not got the product, but i have not received the refund till now, i called them so many times, they said me to wait for days, meanwhile months are going one. I have sent the orders of paytm wallet to them too, but i have not received my refund yet.
