Before we start the tests, a down payment is required upfront.

We accept your payment by PAYPAL, bank transfer and Western Union.

We can guarantee you 100% passing all testing programs for you.

Generally speaking, though we can complete all the testing programs within 7-10 working days, we promise a time limit of a maximum of 20 working days. If we can’t complete all the relevant tests for you in 20 working days, we will give you a full refund.

If you have any question on the terms above, please do not hesitate to contact us at certwind@gmail.com.
