LinkedIN - Poor customer service

Kind of a vanity post here, but a few years ago, around 2010, I signed up for LinkedIN's OpenLink Network. It was free to sign up, and I was not a Premium member. OpenLink Network allows Premium members to communicate with you for free, instead of having to use their credits for InMail. Sounds good right? Well, it was good, until today when I checked my account. Low and behold, I am no longer an OpenLink member. Apparently, LinkedIN feels they can just take away this status from anyone that was an early adopter. This is not the way to treat customers. I have never paid for a LinkedIN membership, however have spent about 1000 bucks the past year advertising jobs on their site. Now, they have lost a faithful early adopter, and have made an enemy out of a paying customer. It's a shame that a company like LinkedIN would treat me this way.
