Hi this is karthikeyan p. I'm a kotak credit card holder. My crn is 98795590.
My credit limit is 20000.
My bill date is every month 20th
Due date is every month 7th
May 20th bill i have to pay by 7th of june.
I was strucked in death issues in my family, so i can't able to pay so i got late payment fee gst and for that levied late payment i got over limit fee and gst and auto debit failure fee and gst i got. I called customer contact centre and asked why this much charges and he explained i said i already said to cancel the auto debit but he said but no one still take complaint and cancel the auto debit may i take the request to cancel the auto debit myside. I said okay and i was okay with him i accepted and request to reverse any charge he said i can't cancel all the charges its nearly 2000. I can cancel only 375ruppes i said my fate okay thanks fr that. And i paid nearly 22000 to get my credit limit of 20000. I always use to pay the whole amount without any pending.

And 13th june i got the mail from them success fully autodebit was cancelled. Screenshot also i attached here.

Now coming to may 20th to june 20th bill.
I have a limit of 20000. I purchased a mobile of 19665. And i make a payment of 200to and make some balance in credit card to eat and eat for 360ruppes after that my credit limit was holding 275. Now max bill is below 19900. And i don't have auto debit becoz it canceled before 13th june itself. Now it showing -1995. Where i used extra for over limit.???
When i canceled already auto debit they can't able to charge that also. But if it is activation also if i don't pay the bills before 7th of july they will charge. It's fair.

I want that -1995 unwanted charges should be reverse totally with gst this time. I don't wanna take responsibilities for bank mistakes and their unwanted charges. Becoz i m doing that past 1year.

I[censored] reverse that all charges for ur mistake i'm ready to pay what i used with in my limits i make a payment before july 7th 20000k.

Or else seriously i'm ready to face the civil score credit score and face the court procedures and close the credit card poor service of kotak mahindra bank and go for serious issues.
