Airtel — balance not updated

Address:

226028

I recharged my airtel digital tv worth rs 510 through payzapp app on line recharge on 24/11/18 with transaction id no.34839943. Till now balance is not credited to my account. On contacting to payzapp they want written mail from airtel, but airtel is saying that transaction id is fraud and refusing to provide the same in written, i want appropriate action against both the companies
