Swiggy — payment refund not happening, promised callback not happening

Address:	Bangalore, Karnataka, 560075

I placed an order on 25th Aug for rs 554 and found out that that Swiggy took 2 different amounts from my account, 554 and 562.50. I had a chat with them the next day and they categorically denied that they had done it and asked that I speak to the bank. I called the bank, blocked net banking, blocked my debit card. Was on my way to the police station the following morning and thought will confirm with Swiggy if they really didnt know about the second payment, this time I got a different story. They now said that they will refund the amount to me as 554 into my bank account and rs 8 into swiggy account. I asked for an email confirmation on this, didnt get one for 24 hours, got on chat and asked for a call, assured one in 24 hours, didnt get one. Sent 2 emails, no reply. Meanwhile the bank closed the complaint and I am unable to use one of my bank account because the ineffecient customer service has no clue what they doing and how to handle/address/resolve customer complaints. Still waiting for a callback, reply to email and the promised refund.
I have decided to NEVER use this pathetic app again and dread having to get stuck with this appalling customer service team ever again.
