Firstly, never write an email upset
Secondly, do not include P-WRX in your reference
Thirdly, if you want to be taken seriously, even if you're upset, don't take rush and make your email sound like it was written by 10 year old.
It will be treated differently if you don't communicate it professionally.
You are one of a few thousand clients, and if you give an organisation a reason to put you on the lower priority, you will be treated as such.

Sorry, I know my post isn't one that is jumping on your bandwagon, but telling it how it is as an outsider.
