Cracked frame

Hi everyone – first time post so please be gentle. I wanted to know whether anyone has experience with cracked carbon frames and the time taken to get a response from the manufacturer on warranty?  It is a two year old bike that has been treated very well, essentially it is cracked on the seat tube and I have never seen a bike experience a crack in this location but wondered if anyone else has? See photo links below. 

In terms of submitting a warranty claim, I have taken it to a local bike shop who have submitted a warranty claim on my behalf which happened about a month ago, I’ve been following up with them weekly and they’ve told me that it is a waiting game and there is no known timeframe for the manufacturer to get back to me even with a response. Given it has now been exactly one month since the claim has been submitted, I decided to contact the manufacturer directly and all they indicated was they need time to understand the situation – a month to understand the photos that were supplied seems like its stretching the friendship? They have not asked for additional photos or further information, or even to ship them frame to them – just silence. 

Now to put this in context, I am a big fan of the brand of my bike and the bike itself, however not receiving any feedback at all for a month is making me question my allegiance to the brand. Is this normal as it has never happened to me in the past?
