Acer India — Not cancelling my order.

Hi,
I ordered a laptop of rs 94500, but after placing it within 1- 2 hours i realised that i have some other financial issues, so went to cancel but there was no such mention that it cant be cancelled in the site.However, after reading their terms and conditions i came to know that till order is in processing stage it can be cancelled.I sent the mail regarding the same within 2 hours of placing order.But now they are not replying properly..Its been more than 2 days.
