You mentioned blocking for reasons of sending more than one ticket. However my second ticket was sent 4 days after there was no response, despite the urgency (which is over the 48h interval for CS response).
I tried to search on the forum but I found no thread about a similar situation.
I don’t think it is possible for CS to unilaterally decide to “block” or not respond on purpose, without any violation being reported or any warning to the Seller, since the Seller continues to pay for this service of Customer Support. All this time, I am assuming I can contact Fiverr.
Even so, is there any stipulation in the TOS that says Customer Service can unilaterally decide to interrupt Customer Service, on purpose, deliberately, for certain users or certain questions, and for which reasons? Otherwise it feels like a breach to me.
As a 5 star Seller with almost 1000 reviews, and as a business partner and customer of Fiverr for many years, with no issues, if indeed this is possible, for CS to actually refuse to answer my ticket because I sent 2 more tickets due to lack of answer in due time will be a reason to take my shop some place else.
