I sent Sony some feedback a very long time ago. Yesterday I received sort of a reply from them (in Finnish, with spelling mistakes):
Hyvä asiakas, Tehdessämme rutiini tarkastusta ohjelmaan joka käsittelee sähköpostimme, huomasimme teknisen vian joka valitettavasti on tuhonnut viestinne sisällön. Onglenma on nyt korjattu ja pyytäisimmekin teitä lähettämään viestinne uudelleen, jos vielä tarvitsette apua Sonyn asiakaspalvelusta. Pahoittelemme tapahtunutta ja siitä koitunutta vaivaa. Ystävällisesti Sony Support support@sony.fi
My loose translation:
Dear customer, While running a routine check on our e-mail software, we found a technical error which had unfortunately destroyed the contents of your message. The problem is now solved and we ask that you send your message again if you still need help from our customer service. We apologize for the inconvenience.
No need to apologize, I’ll take the quality of your customer service into account next time I’m considering to buy a product from Sony. Just wondering, perhaps it was a Sony rootkit that deleted my message? Mybe somebody had popped a DRM infested Sony CD in their mail server. Just a thought.
lol
:D
