I have been contacted by a potential buyer for my gig and he requests me to call him should I call.
Customer is forcing me to contact him on phone should I go ahead or I should refrain from such things
Of course not. It’s against fiver TOS
Report and block. Don’t put your account in danger for someone who didn’t read TOS. And read TOS yourself.
You don’t need to talk to anyone on the phone. He isn’t forcing you either. Don’t violate the rules, they are for your own protection.
Just ignore it. And let him know about the rules.
