I recharged my jio number of 399 but the amount was deducted rs 2399 fm my account and there was a cash back voucher of rs 2000 of bigbazaar in my order whereas I didn't click on it as the city i was residing doesn't have any big bazaar outlet .so where can i use the cashback voucher .so I want that the money should be return to my bank account.
