My name is ramkumar. I am karur vysya bank customer. I transferred amount to my brother account via phonepe. Phonpe transaction says failed. But amount is debited from my account [protected] on 07/07/2020 time 2.50 pm. My amount is not yet credited to amy account. I called customer care. They are not providing answer properly. Worst customer service. My amount 3000 is still lost.
