I want to hire a freelancer, but warnings come saying: "You have not deposited a valid billing method with Upwork, please correct it before you submit an offer.", "Sorry, we are unable to authorize this credit card...".
I have a note saying "charge failed", so I cannot hire the freelancer. It is my first time as a client at Upwork and I use a visa card.
Help me to solve this issue as soon as possible, please.
