Anyone used My Poupette authentication lately?

I view of the disgraceful behaviour by MyPoupette of which I have been a member for many years I have just sent this email:

Dear Angie,

It is with great regret that I must ask you not to deduct my subscription from my account when it comes due.
I am xxxxxxxxxxx on ebay.
When I joined your organisation it held prestige as a seller of authentic items. Alas this reputation has been sullied by members selling fakes & by your shocking customer service regarding authentications. People are now saying on purse forums that no self respecting seller would be associated with your organisation. I am sorry that you have let your business slip so badly but that is not my concern, mine is my reputation & MPRS no longer has respect so please confirm by return that when my subscription expires that you will not recharge

I am sorry again that it has come to this

regards
Roz
