This has happened to me too - except they claimed my design of the website as their own creation on their own website when in fact they were just updating/maintaining the website! :injured:
I think it's difficult to remain unaffected by the actions of your clients - I take things personally almost in everything I do, including my web design business! I mean if I designed a flyer/website for someone and they liked it but went off and got someone else to do one for them aswell and in the end chose the other person - that would bug the hell out of me - either they work with me or they don't - perhaps I'm too extreme :lol: :rolleyes:
But I can understand how you are put out by it, I would be the same - I think I would offer to update the site for free especially if it was part of my business portfolio. I wouldn't want someone's dodgy updates to reflect bad on my work!
