Idea Cellular — Bad Processing of requests

sir,
I am an idea customer. I requested for gprs service on my no. [protected]on 7Aug, 2009 the service was activated at 5:15 pm on the same day but when I requested for deactivation on 9 Aug 2009, they transfered the request and my service was deactivated on 10Aug, 2009 at 3:00 pm and still they deducted the balance for the next day at 6:30 p.m. on the same day.
and when I called customer care they refused to handle my complent.
Idea should learn to handle their customers.
