How can I remove the current Payoneer ID and add a new one?
I have found information on this page https://support.upwork.com/hc/en-us/articles/211063988-Payoneer that it's necessary to contact the Customer Suppor, but I can not find any way to submit a customer support request.

Why is there no Customer service?? It's incredible you guys have this platform with absolutely no way to get in touch real time with a rep. Terrible.

Hi Brian,

If you're looking to remove your Payoneer payment method you can find instructions here. If you're having issues with this, could you please share some details so we could help?
