Reply from online on 02/04/20 *dear sir/madam, kindly wait 5-6 amount will be credit to customer account.*
What does 5-6 means, hour or day or month or year? 27 days to go no information when my money come, and bank cross the time bounding. This is a delicate time without money i can't do. 15000 rupees it not just less amount. I want my money back with compensation.
