Hi Stianos - you haven't provided much of the detail which would help someone give you some solid suggestions. However, I will try with what little you have provided. Providers like Paypal and Stripe tend to approve all applications up front, then weed out the merchant categories they don't like after merchants have already started processing. This may have been what happened to you. You are definitely better off being completely honest about your product/service and business model, and getting an approval up front from a high risk provider based on what you are actually selling/doing. There are high risk providers out there; however, which provider would work for you depends on all kinds of factors like where you are located, what you sell, your payment processing history, etc. I recently wrote an article about high risk processing which might help you out. I don't know how to private message on this message board but if you know how to private message me I could send you a link to the article.
