DashaIndia's sugar coated words really attact you. Once you made your payment you will start seeing their real faces. I am one of the victim in their hands. I am writing this in my own experience that I had with dashaindia. If any one planned to go for dashaindia think for a million of times before you take your decision.
Most of the times we get error message while browsing their website. Their client interface is not that much user-fiendly. In worst case, the SMS’s will be delivered only after 24 hours. You wont get your delivery report immediately. They wont reply to your E-Mails. They never attend your phone calls. They dont have any defined support system. You cannot send SMS greater than 160 characters. They dont have any proper documentation for Client API integration. My suggestion is "Never Ever go for it".
