Flipkart — my order cancel and my account blocked

Address:

Ludhiana, Punjab, 141003

I have ordered 1 mobile to my brother. And now flipkart blocked my account saying that i am reselling products. Without inquiry, how can they block my account. Please take necessary action on them. How can they insult me. If i want to do so, i can create multiple accounts, why i use same account. Please check this. Thank You
