Airtel — message always gets failed to send

Address: Coimbatore, Tamil Nadu

I'm not able to send message... It's getting failed wat may be the reason i have tired to contact airtel customer care... But i am not able to contact the customer care... I'm oly getting others services... Pls tell me a solution... The customer care service also doesn't not help me to sort out the prob... I'm just need to know why message is always getting failed to send... But you guys need a summary of 350 words... Tell me wether i'm writing a essay writing competition or registring a complaint...
