SRAM eTap Aero - Part 3

Just a brief update on my last posting about the SRAM eTap Aero kit. I now have a fully functional eTap set up on my main time trial bike, almost two months to the day that I first reported the defective blipbox to the mail order retailer. Since mid-December, I've periodically communicated with the retailer by email (though it's not been obvious who to email) and via Twitter direct messaging. I've also contacted SRAM via Twitter and then email, to try and get a handle on where the problem has been. As far as I can tell, there have been supply chain problems somewhere along the line, though there seem to be some startling communication problems within the retailer. Anyway on Tuesday I received an email telling me the replacement blipbox had been packed and posted for next day delivery. About half an hour later, I received a second email (from an other person at the retailer) saying that the blipbox had been listed as present in a consignment, but that it was missing, so a further delay was to be expected. I replied, querying this information, and got another email saying they'd got it wrong, and the blipbox was indeed out for delivery. And it arrived, first thing the following morning! That evening, I fitted it, paired the gear mechs, and all is now fine with my time trial bike. The whole sorry tale has been a bit of a saga, and I am at least rather pleased it happen out of the main racing season.
