So, you have multiple issues here but since you have an active Fiverr account, you should be able to eventually fix it. Two things you’ll need to do are read the Terms of Service very carefully and practice not just patience, but extreme patience.
What got you in trouble in the beginning was breaking the Terms, maybe because you didn’t read them. Then you should have written one single polite apology to Customer Support and asked them for suggestions on regaining your levels. They probably would have told you that you could keep selling and after they saw you staying in the rules, you’d have re-earned your levels.
Instead, you got impatient and instead of focusing on impressing Fiverr with good behavior, you spammed them. My guess is that you did it because they didn’t respond on your timeline. I see you still have problems with patience. Today you inboxed me and then when I didn’t respond in a few hours, you wrote me again. No one likes that, so Fiverr blocked your support account for spam.
I doubt they will leave it forever if you can get your head together, but now you have a lot to fix. First, you’ll need to leave CS completely alone for at least 45 days. Second, during those days, done panic over withdrawals. Just complete as many small orders as you can, honest sales, no rule breaking. I say small sales because since you are so close to losing your account you don’t want to risk big money sales that could end in refunds. Show Fiverr you are here to do this right.
After 45 or more days, see if your support account is unblocked. If so, thank them, apologize again and ask if there is anything else you can do to get levels back and address any withdrawal issues. Then wait as long as it takes. They might give you everything or they might want to to send proof of identity
I know that sounds tough, but remember, if you hadn’t broken rules and become impatient, it wouldn’t have happened. Hang in and see if you can step up and put this account back together. Otherwise, you can always try other sites out there.
