HDFC Bank — Wrong commitment of Jumbo loan on credit card

Address: India

Sir,
Today I received a call from [protected], a operator called Riya told me that HDFC Bank offering me loan against credit card at flat 10.25% to me of Rs 2, 40, 000 . I like that offer but she started to jiggling with words and calculation like loan at 19.06 but it's 10.25 % flat. I said your EMI calculation are not matching with me but she said you are miscalculating your Loan it's 10.25% . So I said Ok. But after checking at HDFC BANK website it shows 19.06%, I called again at her number, she told me that it's 10.25% sir, I told her about website she said that she will transfer my call to her senior but she never did. I called again but she said she will call back but I never received her call. Now my credit card account shows loan at 19.25% .
I want to complain about this cheating and malpractice of disbursing loan
Please look into this matter and CANCEL MY LOAN otherwise I have to go to RM and banking ombudsman for this malpractice of telecallers of HDFC BANK
