On dated 2012 somebody called on my mobile no. & Told me that seeing my hdfc bank's credit card payment track record dining plus (dp) is providing me a gift vr,holiday tour package & dining plus discount card of 20% . The dp people enumerated too many discount benefits of dp card, on hearing the above I DID doubt and asked why your company is giving so much offers and what is your profit in it? they said your payment track record is very good with hdfc bank and we have tie ups with the banks .During the conversation they asked for my hdfc bank credit card no.& Validity,for which I objected but they assured me that it was required for just verification only as they had these detail already .So I provided the same .On next day itself I received a sms from hdfcbank (I.E. On 2012 at 16:08 )that my credit card has been utilized for rs 5499/-In mumbai at dining plus.Due to being too much busy I could not take any action till now.The dining plus has cheated me by utilising my hdfc bank credit card for rs 5499/-Without my consent. Without any written communication from the customer or any sign on the form , how dining plus could make the transaction?, please initiate necessary action against dining plus & help me to recover my lost money.
