USENEXT FREE TRIAL Internet

I was never actually charged a second time because I canceled my PayPal auto payments, because i could find no info on how to cancel on their website. I thought all was well and then I got an email stating i owe this company..

The outstanding total claim is specified as follows: 

Now just about every month i get an email with a new outstanding amount that is substantially higher than the first amount that they are saying im obligated to pay.. Since when are you obligated to pay for a prepaid service that you are only able to use AFTER you make a successful payment? I never even used the trial I have made every attempt to make peace with these people and come to an agreement but it seems like they just want to scam any and everybody out of their money.  I have added some emails they sent me along with some insertions as to where they themselves say in so many words that their service is prepaid. 

I will now be contacting the internet fraud center to see what they say about all of this.

I got this email in the beginning of July 2016..

The actual claim added up to 161,02 EUR so far and results from the delivery of goods/rendering of services plus extra costs due to the delay in payment.
