I know full well you're not a CS agent and this isn't really your job, but I thought someone there should know about this.
I had the VIP subscription that gives a 15% discount on boxes purchased with gold and a 10% bonus on gold purchased with packages. Last weekend, during what was being called VIP appreciation week, the specials section showed that I would get a 20% bonus instead of the usual 10%. So I made a few purchases, then I realized I didn't receive the advertised 20% bonus (I did receive the usual 10%).
I raised the issue with customer service (complete with screenshots), and they readily acknowledged that I was offered a 20% bonus and that I did not recieve it. However, they are unwilling to either provide the bonus advertised or refund the purchase - I have stated that either is acceptable to me.
They have claimed that the 20% offer was displayed in error, and that it should have only offered 10%. I have explained that I don't believe that matters and that the 20% bonus was part of the reason I made the purchases. I have asked for an explanation as to how glu believes its position to be legal, but I have not been able to get an answer.
I don't know if you can or will do anything with this information. It is not a significant amount of gold, but the gold is hardly the point anymore.
I guess I still have enough faith in glu that I don't believe knowingly violating fair trade laws is part of the business plan and that someone aside from frontline CS staff would want to know about something like this.
