First, you should check your internet browser.
In case of inner browser errors sometimes the payments could not be processed for reasons beyond.
In this case we recommend to use Google Chrome and Mozilla Firefox to proceed payments.
The problems also can appear if you are trying to use Visa Electron or Maestro cards. Unfortunately the payments could not be processed from these types of cards.
Also the payment could be regarded as not secure by the bank servers. In this case you should connect other Wi-fi network or try to process payment from another device.
If the payment still could not be processed you should write us on firstname.lastname@example.org
