Several years ago I set up a site on 500px as a second site. In their subscription they offer a general photo site and a portfolio. Even though I did not opt for automatic renewal, they charged my credit card for the renewal AND removed the portfolio yesterday. I emailed them right way, and they answered right away:
"***Please be advised, our Customer Excellence team will be out of office to observe a holiday in Canada on Friday, May 19th and we will return on Tuesday, May 23rd. You may experience a delay in response to your request.***"
I've been on PBase over eleven years, I've never had my card charged without my authorization and have never had any images removed. I just wanted to let you all know in case you're thinking of moving to 500px.
