This has to be one of the worst companies ever on Appsumo. So I bought 60 monthly credits to make Ahref searches. But what they don't tell you is there's another credit system and you get 30 only and if that runs out you need to pay So if you want to see the traffic and data from Ahref you need to buy credits and that 60 credits that I already have won't work.  
And to add salt to the wound they promised everyone if they bought Dibz and Base another app they own, they will increase your limit but only after the refund window expires. So what happens if you try to message them for those extra credits? You guessed it they went ghost.
