PhonePe — it has been more than a month to execute a refund for an unsuccessful payment to yatra

I tried to book flight ticket in yatra using phonepe on 7th feb'18. But yatra didn't received the amt of rs 4010 which was deducted from my account. I raised this issue with phonepe after getting confirmation from yatra with ticket id 7632660 on 10th feb. But since then customer care people are repeatedly saying that the issue has been with their techinical team which is working on it and i will get the refund soon. Even they asked for 3 deadlines like 16th/27th feb/5th mar which they failed to meet. I don't know if one month time is too less to resolve this type of issue. I have sent more than 10 emails and talked to them several times but could not get a resolution. Infact many times they have misguided me giving false information in emails that my issue has been resolved. I am quite annoyed by such type of irresponsible activities of phonepe
