HDFC Bank — Transaction dispute

Address: 560025

Website: www.hdfcbank.com

I was using hdfc hdfc credit card ([protected])
On 19-aug-2015, i've made a transaction of 1300 inr at m/s accelyst solutions pvt mumbai ind. But my monthly statement reflect 1292 inr amount. I file a complaint against this amount and simultaneously i made the payment for balance amount (Around 20k).
As per my discussion with hdfc customer care, they blocked my card as they thought it was hacked.
They took 3 to 4 month to know that i got some 8rs discount from accelyst solutions. So i was ready to pay 1292 amount and asked them to deduct the extra charge (I have that on my mail). As it was not my fault, hdfc took 3 – 4 months to resolve this.

Still now i am ready to pay that amount and close this asap. But didn’t get a single response from hdf bank. Now i am getting calls from random people to pay an amount of 6845 inr.

Attached mail screen shot for reference.

Please help me out in this to resolve this issue asap.
