Eh, I have to disagree with a few things, but you do have some valid points.
I was partnered with CN from February 2014 until ~May 2015. During those 15 months, they only once (actually twice, but second time it was resolved promptly) had issues with payments and everything was communicated well and issue with PayPal was resolved within a week or little more. What was happening after that, I'm not sure, but PayPal can limit your account multiple times a year without a doubt. I work for a company that was acquired by another billion+ dollar company last year and we also had issues with PayPal, which was essential for our business. However, all the issues were normally resolved within a few days (if even that long!), normally a few phone calls and sending some documentation was enough. Mind you, this is an US company, so laws and other stuff when dealing with PayPal might be different in UK, but I do feel CN took too long resolving their issues with PP.
When it comes to their promises... well yeah, there were a few, most notably Creative Suite that was announced at the end of 2014, pre-beta invites were sent out in early 2015 but to this day, it still hasn't been finished. That sucks and someone should get fired for that. However, they used to do some really cool giveaways - I actually won a decent headset that I've been using for a while until I upgraded to Logitech one and they had cool series where they featured various channels and had others comment about them and give their thoughts how those channels could be improved.
Creative Nation WAS great, I've been extremely active on their forums at the time and I knew of all the problems, if there were any. However, I would imagine things were further down the hill in Q3 2015 and later on, as seen nowadays by various threads here and on CN forums. I agree with Styxie's comment from other thread, Creative Nation needs to rebrand, they need to do serious changes if they don't want to lose even more partners and get even more negative feedback from partners.
