You've tried in your own aspect to suggest payment option other than PayPal for them. But such kind of site are simply happy with PayPal they won't like to add any other because if the love they have for PayPal.I have contacted their support team and they have told me that they are a US-based company and they cannot pay through Payeer and Perfect Money because these two payment options are not available in the United States. I wish if they could also add some other payment methods other than PayPal payment option.
