I bought a Cloud licence, but I became a member of an unknown company from Asia

Around April, I bought a cloud license from a reputable Hungarian retailer with an invoice. I was asked in an email to log in with my email address and I would receive the package. When I logged in, it turned out that I had become a team member of an Italian printing company I don't know. A few weeks later, I was asked to sign up again, but then I was a team member of an Asian company. I dare not use this subscription. I have already been mistreated on other cloud hosting. Is this situation ok or what should I do? P. Kéri (HU)
