Ibill - hehehehe
Its the most fun billing i have ever seen.
From the last:
We used ibill as a secondary billing system, from time to time some of our clients used it to transfer money(very rarely).
Except our previous "lifetime deposit"

we collected new minimum payment sum at our account. Three months passed... We asked ibill about our money(softly-softly). We have heared a lot of fun things from ibill but this one is the best.
They answered that sum at our account is less then minimum payment amount and its half of the sum we see in our account.
So we see in our stats one ammount, but ibill tries to persuade us that we have another

So we throwed out it from our site.
