wespro android 2.3 tablet not working with 3g dongle

Location/place: haridwar

Name of company/service: naaptol

I have purchased a new 1 GHz android 2.3 tablet. And on their ad it is showing that it will work with 3g dongle but its not working. And none of their customer care executive knows how to conect 3G dongle. NAAPtol is cheating with buyers.
