Stolen bikes

Thanks GA2G, I've been considering options after the local store management weren't able to help (really useless). They don't appear to be accepting any liability or that there's any recourse.

It was directly under the CCTV cameras (which was why I kept it there), but apparently they weren't operating due to the refurbishment...

There is probably a separate camera that spotted you coming into the complex, if not parking up.
It will also show that you don't leave with your bike. They don't only have one camera....I'm sure of that.
