IDFC Bank — Repeated Daily Spamming

Dear sir,
As brought out earlier, I continue to get at least three spam mails from daily from IDFC BANK. This cheap and worthless company is in habit of spamming and despite numerous complaints has not stopped spamming despite receiving my complaint through email and through you.
I don't understand what they are trying to prove except that they are renowned SPAMMERS. As I get several mails from them regarding Credit cards, loans etc. It looks like there is an intense war going on regarding selling more and more Credit cads. I have sent many mails to their Head Customer service with copies to banking [protected]@RBI chandigrah.
VERY soon they will all come under data protection cat and then will be liable for prosecution. Cheap companies don't care for PRIVACY, Customer Grievances and are only self centered. and above all GREEDY.
