I am using this application for 8-9 months. But what I have noticed is this application lag so much. Most of the time when I did a transaction it failed. 1/4th time the transaction became successfull. The most bad experience was when I made a payment of rs 399 with a rs50 voucher but the transaction failed but theke reduct the amount from my bank. Then when I complained at jio customer care the did not response well. Also they did not give me back my rs50 voucher. After a long period of 18 days they finally back my reducted amount to my bank account but till today they did not give me back my voucher. Very poor service.
