Hello Dimas,

but i get no answer and so i sent a reminder with the same link and get no answer again.
Please let us know your reason for asking refund . We are only able to accept your request if you encounter any unfix-able issues that cannot be resolved by us or if our software does not have any features that we advertise in the features list.
Hope your issue is solvable though, then our support team can sort things out for you swiftly.
