I do not have a phone number to call and the client service that I contacted using the form on the website does not reply.
What to do? Anybody has experienced the same problem?
How long since you submitted a ticket? It usually takes around 6-24hrs for customer services to reply to a ticket so maybe you should wait a little more but if it's already more than 24hrs then that's concerning, maybe try to submit another ticket or try to contact their live support if they have any.
Yes give them at least 24 hours. I've been using fiver for ages now and their support is a little bit slow but when it comes to money they do give their clients an outstanding service.
The first time they refunded the money without any fees.
