As the reseller involved here - I can state that we did not "commandeer all renewals related to the email address" - ESET is a partner channel based company - if you you register/purchase licenses through a reseller, ESET than allocates your account - identified by email address, to the reseller. If you want to change resellers, or deal directly with ESET instead of the reseller - then contacting ESET and asking for that purchase option should override the reseller arrangement. ESET is, in the end - going to benefit from a happy customer more than anything.
That said - we did speak on the phone yesterday - and I was able to get this license renewed - even though the ESET websites said it could not be renewed - we got you a renewal processed at renewal rates. We can sometimes work "magic" that the ESET website cannot.
We're a small family run reseller- although we have a LOT of ESET customers - we continue to do well selling ESET software solutions because we are in the customer service business - we happen to sell a product we love and use ourselves - which is the ESET software.
I hope that my explanation of the way ESET handled your account - ie, you are directed to a reseller based on the past relationship - keyed on your EMAIL address - not the license itself has cleared up any confusion - we certainly didn't commandeer your business!
