I have paid off my loan on 13th of this month.

Since then an amount of 590 has been getting deducted from my HDFC Bank. I have been trying to get in touch with customer care HDFC bank since 2 days I called more then 10-20 time and was on queue saying that all their executives are busy. They make me wait for 10 minutes and simply disconnect the call. This is really frustrating, I need a refund for the same as they have deducted more than 2500 as .ach debit return charge for a loan which is already cleared. Worst Customer service ever. I think the number they have provided is a fake.
