I want to delete my upwork account because i opened it when i was much younger and i haven't even been able to use it at all as it has always been suspended.
I want it closed; i want to begin again from the scratch and have no difficulties.
You can only have one account, and it's unlikely Upwork will allow you to close one and open another. Why was it suspended? If your current account is suspended then you can't just open a new one to remove the suspension.
You can only have one account on Upwork. Creating a duplicate may lead to its suspension. Please, check the notifications the team sent you about your account suspension and follow their instructions to solve the issue and restore your current account.
