I ordered a GSM phone on Timtara.com. I read lot of reviews in mouthshut and other consumer forums about how Timtara.com is cheating customers. It is a big cheating website. [Read my review about timtara.com in mouthshut.com].
I spoke with CCAvenue support and sent mails also. Technically they can easily ban Timtara.com from their network because I gave so many instances where Timtara.com had cheated people. But CCAvenue did not help me and they continue to encourage Cheating websites like Timtara.com.
