Dear sir,
I have been un neccessorily charged with autodebit charges for my credit card since two month, even though i have already paid all my dues on and one day before the due date. (Manualy)
But previously i have paid my dues similarli on due date since 1 and 1/2 year there was'nt any amount charged on me but since last two months the autodebit charges has been levied on me. I ahve talked to your customer care executive first time he told me the the amount will be reversed but there wasn't and also he did't informed me of the exact reason for the charges.
And the again the autodebit charges has be levied on the second months even i have paid one day before.
Later on one of your executive told me that i have to pay 3 days before and another executive told me 5 days before.
Please tell me which is currect.
Kindly do the neeful to please reverse my autodebit charge whic is incurrect even after paying my dues on time.

With best regards
Vivek prajapati
