Sponsor from UK using epochstats.com not paying....

Hello,

I have been working with a sponsor from UK, a small site, amateur, for years they
worked with CCBILL, and ccbill payed me on time the revshare of 50%.

Then a few years ago they switched to EPOCH, and epoch ONLY pays to
the sponsor, the affiliate can see the traffic, sales and rebills, but the monthly
check goes to the sponsor.

From that time on, the problem started, they were always late on paymenths
(now via paypal) and a debt started to accumulate, so, each month i was making
u$600 in sales and rebills (50% revshare); so epoch was sending them the check
for the full amont, and they were paying me lets say 400/500 via paypal.

I tried to contact them about this many many many times, i was getting some replies,
saying i will get paid. But the debt keep growing.

Now it seems they have stopped paying at all, as two full months passed without
any paymenth, and theres an accumulated debt.

My question is: is something i can do? mostly with epoch?

I dont have the funds to start some legal issue. And im actually in South America.

Is a shame because is a small amateur site, i have been working with them
for many years, but it seems they dont care about me anymore.

Any suggestions will be more than welcome.

Thanks for reading , best,
