Ola Cabs / Ani Technologies — ola postpaid bill money deducted twice

Sir,
My ola postpaid money was due 869rs. Last month and i tried to settle it through netbanking on 26th april 2019. The above mentioned amount got deducted from my bank account but the same was not reflected in the ola account. Again i settled the bill by paying the full amount of 869 rs as there was late fee being charged by ola for late payment and the amount got cleared from the ola money account. The rs. Deducted from the first failed transaction has not been credited to my account yet though it has been 7 days from the event. I even mailed ola customer care thrice regarding the issue but they are not even responding. I am highly inconvenienced. Please look into the matter.
