iCandy Peach Jogger - double help

hello - first time posting but I've read threads before and you all seem super helpful :-)

so we have an iCandy peach jogger travel system and love it. However just found we are expectig a second baby next year and our little girl will be nearly 2.

it appears the iCandy peach jogger can't be converted to a double! I am so mad we weren't told this when we bought it but anyway we did: so now what to do going forward. 

I emailed iCandy asking if I can just buy the chassis to an iCandy peach but they said I can't. 

has anyone else been in this situation?

thanks
