Exide Industries — battery not replaced even though in warranty period

Address:

New Delhi, Delhi, 110024

I have purchased a new exide battery from the dealer 'battery Tyre house, A539, double storey kalkaji, new Delhi 19 ' referred by customer care [protected].
The details of purchase are as follows:
Date of purchase - 15th Dec 2018,
Battery type- FMI0-MREDDIN44LH
Battery serial no. - A5A8B023820 5A83

Just after one week of purchase, car battery got discharged completely. I contacted the dealer, he advised to contact exide customer care to get battery charged. The dealer also advised that he can't replace the battery. Then I contacted the exide customer care, they took the battery for charging and returned after five days . The senior at customercare also advised that only dealer can replace, we at Exide cant replace the battery. The service engineer advised me that the dealer has given old manufactured battery, which is why it is getting discharged.
unfortunately again after a week the same problem surfaced, the battery got discharged completely and the car couldn't start. Now again I have got the battery charged by exide care by contacting exide customer care as the only solution advised by them.

Several times my car battery has been charged. As the problem persisted, the technician visited on complaint on 11th Feb 2019. He measured volt of battery, he found it to be low and removed the battery from car terminal. He asked me to keep checking the battery voltage, report him if it goes down. On checking the battery volt on 14th Feb, I found it to be decreasing considerably. Hence, I called the exide care immediately, but again they advised that tomorrow i.e. on 15th Feb they will send technician again to check and prepare report. They also said they can't replace the battery. Now I urge you to either replace the battery with a fresh one OR kindly REFUND my full amount at earliest.
Now I am fed up with the battery provided by the dealer of exide and the service of exide.
