Whatsapp — my whatsapp number is banned

Address:	Indore, Madhya Pradesh, 452001
Website:	Whatsapp application

Dear sir, my whatsapp number is banned by whatsapp, i don't know the reason.. When i mailed on support of whatsapp for help then there comes computer generated reply and after that i mailed about 30-40 times and tried to contact whatsapp for help, but they have not replied again.. I am using whatsapp since many years but i never did anything wrong, i never used any third party application, i only used official version of whatsapp. I never created any kind of group on whatsapp, i never send any msg to any unknown number and also i never send bulk messages then why my number got banned.. Kindly help me as i am connected to my family, friends and office colleagues through whatsapp only.. My number is banned since 4 days and i am very frustrated and don't know what to do as whatsapp support is not giving any reply nor unbanning my number.. Kindly unbanned my number.. My name is gagan sharma. My whatsapp number is [protected] and email id is '[protected]@gmail.com.. Please help to unbanned my number.
Thanks & regards
