[Resolved]  HDFC Bank — transaction reversed but not reflected in my credit card

I tried purchasing in amazon so my first transaction money deduced and after sometime payment decline. So i tried again second time same happened. Totally twice money deduced and twice payment declined.
Next day morning i got two messages saying amazon is credited/reversed transaction on[protected].
So i waited a week and checking my card statement but funds are not credited. I tried contacting hdfc customer care not even taking this things.
Can anyone please look into it.
