There was an offer on flipkart in big billion days sale which was on 10 oct 2018 to 14 oct 2018 that if i will recharge for the amount greater than rs.300 i will get rs.150 instant discount so i rechargerd with rs.399 and it showed me that rs150 instant discount applied and i had to pay rs.249 so i paid it but due to rupay card of paytm bank the amount doesn't show in the otp sms and i paid after that i checked my bank statement it showed they deducted rs.399 from my account. When i contacted they said they will help me within 24hrs and then they closed my ticket and i didn't got any solution.
