SBI Credit Card — Late fees, GST and Interest charges (Intentionally charged excessively from last 6 months)

Address:

Hyderabad, Andhra Pradesh

Dear sir, I, Indira Priyadarsini, am a sbi credit(Master card no. XXXX XXXX XXXX 8148) holder since last three years.I made of payment is usually by online banking thru State bank of Hyderabad.Usually the due date falls on 25th of the next month of the previous month credit amount. During such a long period, I never fails to pay any dues. I was later for few months but from few 6 months i m paying the amount on time before 22nd day of every monh.I observed from the months of february 2015 statement that sbi has charged me (fees(late fees), GST and Interest charges) about Rs.670 from last 6 months late fee+gst+interest. I am not sure why and how. Who does the mistake to victimize me and pay the penalty for it. I request their management through you to look into it and make the necessary correction on the next month bill.I request the claim back to my payments from last 6 months which is unneccessary payings. Plz sort it as soon as possible.Thanks and regards, Indira Priyadarsini N
