You are both right. Except I am not angry with a customer support agent and it is definitely not about the points. The thing that is upsetting me is how they handled the error....here are some points bye bye now.

The thing is, I noticed it. How many people don't. So, that alone should have been more concern to them. It must be something wrong with a loyalty system. I do not care about assistants lack of or no knowledge, but once the manager was informed about it, I think it should been a big deal. Yet, it wasn't. I did not go there for apologies or comps. I did not ask for the comps to be credited to me. ...

Thanks again for the responses!
