Advice on best way to air wedding grievances

On the whole, our wedding was amazing and fantastic. However, there were a few things that went on that we were both extremely unhappy about. I've waited a month for the dust to settle and I still feel these issues need to be addressed and I just wanted to get some advice on the best way to handle it. My feeling is that, since it's after our wedding and everyone has been paid, there is no point in attempting to contact those that we are unhappy with. They're not really going to care...

What are your thoughts? Is there anything to be gained by contacting them and making my feelings known, or should I just resort to posting reviews online?

I would say it depends... are these vendors? or friends? family?
Honesty is usually best its all in how the message is delivered.

Ahh.. I should have specified. Our issue was with our venue. I went ahead and posted a review anyway. Thanks

I would say to put everything in writing, and also document all attempts you make to get them to rectify their mistakes.

i would take it as high up as you can. just keep demanding to speak to supervisor after supervisor.
