Reliance Jio Infocomm — number wrongly recharged due to jio app number

I have two jio numbers. While recharging from my jio app i switched from default account to the second number for which i was trying to activate international roaming. However, there was an error by the jio app as it set the recharge for my default number. The recharge was worth inr 1100 and now jio is not ready to refund or retract the transaction. This is fraud as they are penalizing customer for their own mistake
