Avoid them at all cost! I'm with this service for more than a year. I never had ANY good client at all, although I paid 40 EUR per each "opportunity". After I've decided to forget and not to deal with them anymore, they sent me an "offer": "Essayez Premium Gratuitement
Maxim, dès le Lundi 21 décembre 2020 (12:00 PM UTC), nous vous donnons accès à StarOfService Premium pour toute la semaine, et cela sans débourser une seul centime! Vous ne rêvez pas, il s'agit bien d'un essai 100% gratuit de l'offre Premium."
Which translates litterally as "try our Premium offer for free for one week". And then the list of perks goes on. But the price of a Premium was never mentioned!
I've tried. Forgot to unsubscribe before it was expired and guess what - the morning 28 December they charge me 285(!) EURO per 3 month for the Premium!
I've tried to contact them several times - ALL IN VAIN.
The biggest crookery I've ever faced in my life!
I will try to get this money back, but I doubt if this will ever work.
