I've had very positive experinces with AG's CS, but with every business you can have 99 great people and 3 bad eggs.

I think the problem with the CS who was so "kind" as to let you have the discount was that you mentioned you got it from the internet. From what I've noticed if you do not notify them that you have a code at the beginning of the order they have to go back. I always start by saying and I have a code before I start ordering. Sometimes even when i say this they forget and have to go back, which they are always more than happy to do for me. I think this person didn't want to be bothered and be put through the extra steps... because they had to do it they made it sound like they were doing you a favor.

Its a classic... They don't want to be here and are going to make you suffer for making them.

Next time just say you have a code, or a friend of yours gave you this code as they weren't going to use it. Its published on a piece of mail thats really made for the public. The person receiving the code doesn't sign a contract of confidentiality.
