Enterprise SMS Gupshup : Issues in understanding the packages

I wanted to support sending SMS from my web site and registered with enterprise smsgupshup.

The only page I get after login is the the one prompting me to buy the SMS credits instead of explaining what the product does, differences between the various packs etc.

On the top of it, they call "Messaging Revenue" which is very confusing. As I understand it, it should be called "Price/Cost" :-)

Now, I am unable to understand why one would go for an "ace small" pack compared to a "promo small" pack if for the same price, one is able to send more messages.

Also, they are so shady that they dont show anything else you actually make a purchase. I couldnt find any place where the difference between ace/promo/power packs is given.

Overall, I dont understand how they can do such a shabby job on this.

Update: (after finding the details from some ebay sites, yet to find what is "power pack"
Update: Just spoke to gupshup call center (very friendly), got the details of all the packs which are updated below.
