You better get ready for a long and hard fight to get your credits. It took two weeks before I got my measly 8 credits for registering with Second Life.
I've now filed yet another complaint to them for not giving me the credits for 3(!) surveys I have completed. Each one takes an hour or more, so I'm pretty pissed off about it right now. I know I fully completed them too, as I got the feedback form at the end. They're asking for a confirmation email, and those are simply not sent out. Otherwise I would have three of them sitting in my inbox. I don't don't, and yes I've checked my spam folder.
I've given them heaps and heaps of information to identify my replies in their log system, but they won't hear any of it. I just got a standard email some lemming copied into the message field. "Customer service" must be the biggest oxymoron in the English language these days.
I've sent them another reply now. Hopefully being a little firmer will give some kind of results. Being gentle certainly didn't. I have to ask, given all the massive trouble people have to go through every single time to get the credits they deserve from this heinous company, why are they a partner on this site?
