[ADVICE] Rude and New Clients

This is less advice and more a rant. I am a longtime seller on Fiverr and I don't know if it's just me but buyers have gotten pretty rude on Fiverr. I have 250+ orders and a 4.8 rating and every client I have worked with has loved my work.

Some of the recent buyers however, don't care for the work you submit. They don't show any thankfulness, they want responses and changes done in 2.5 seconds and when they fail to communicate, put it on you for being incompetent. And there is nothing on Fiverr that could help sellers resolve these types of issues where the client yelling at you for no reason. This one specific buyer didn't know how Fiverr worked and I had delivered multiple files in the delivery and without confirming if they were happy with the order, completed the order and then came back yelling that the work was not what they asked for- while I had sent everything.

Yes, you are paying me for a service, but you're talking to a human on the other side of the screen? How do you deal with these type of clients?
