Address:

Howrah, West Bengal, 711106

Sir as you said to keep 7101 balance in your accoubt to avoid bounce charge. I kept that amount in my kotak bank account before 1 day. But on the day of ecs i got a message from my bank side that your ecs could not be processed because of insufficient balance i. E rs7158/-
Sir your company did not informed about this amount and also did not send any message. Sir how can i know that suddenly you increase that amount 7101 to 7158. Due to your fault i have to pay 590 bounce charge to my bank.
After getting an sms from my bank i deposited 7158 in my account but till now that amount is not deducted from your side.
Pls solve my problem sir give me noc   replace all
