The two good reviews in Mouthshut are probably written by Sahara themselves. I wish mouthshut would allow 0 or negative ratings. I concur with all the negative reviews here. Wish I had read this earlier before booking their service. Their customer service number is a joke - rarely answered. If they do answer, your genuine queries are met with arrogant replies like "This is too small an account for us to answer" etc etc.
Avoid these guys at all cost.
