Sweden – Traffic Payment We Are Interested In Your Opinion

We work with a hosting provider in Sweden. We rent a dedicated server there. The traffic was uneven, from time to time. Sometimes there was no traffic, and sometimes it reached 90Mbit. We bought a configuration with 10,000Gb. Now they sent us the traffic invoice. That has 18Tb if to count according to the 95% system. And in total we used about 12Tb. We didn’t know they counted according to 95%, that wasn’t mentioned in the agreement, it said only about 400sek per TB excluding VAT***. That’s why we thought that we had to pay exactly for the used traffic because if to count according to the 95% system, which means it’s counted per a channel, and the agreement informed only about the Tbs.
