If you are running a Joomla site with Quick2Cart from TechJoomla then you can use RO Payments. You are going to need a contract with a payment service provider like Ingenico, EMS or Stripe to be able to collect the payments. RO Payments does not do the collection itself, RO Payments only facilictates the communication between your website and the payment service provider.
Let me know if I understood you correctly or if you have any further questions.
There is no image attached but I cannot give support for the wordline.com website, I do not operate that website Perhaps it is better to look for an alternative provider if it is so hard to get into contact with them.
