Reliance Jio Infocomm — Bad service of refund

Address:

Mumbai City, Maharashtra, 400018

I have made Recharge of Rs. 303 from Jio Money app on 7th Apr, 2017. The app shows recharge is successful but as per customer care executive, the recharge wasn't take place. So he gave me assurance that my money will be refunded within 7-10 days. 20 days have been passed but refund is not paid to me yet. Whenever I try to call Jio money nobody is attending the call and the jio customer is denying my request saying it is different department. They cant do anything on it. It is like they are cheating the customers. Please help me to resolve this issue.
