both companies are fake companies.
integral: the persons on the website do not exist. the names are created and sounds like old soviet style, but there is nothing behind. their business field is to get paid legislation fees as a "law" of russian federation what is total bullshit due to the fact, that this law does not exist.
kamneft: same like integral ---- if its situated in kazan, tatarstan republic. there is one little real kamneft, but they JUST DEAL INSIDE RUSSIA, not abroad, and its on River UFA...... watch the phonenumbers: moscow numbers in the deepest nowhere of russia.....moscow is everywhere....
they ask cash from their mandates, if you want to get mandate you have to pay a fee, and again you have to pay legislation fees
