Jabong.com — blocked my account and refusing to reactivate it

Jabong has deactivated my account and refusing to give me any details and told that they will not activate my account. Apparently i am not allowed to buy anything anymore on my account due to some transactions. I have made a lots of purchases on the site and for no reason i’m treated like this. They don’t have a solid reason to give or treat me like this and still refusing to activate. It’s no big deals i can open another account with another email id but this is very insulting as i did not do anything wrong and a very bad customer treatment.
