It was only when the CC company said if they didn't respond by a specific date they'd refund me... than 24hrs before the deadline... they emailed me and said 'no faults found, you need to pick it up'
But as I'd already rejected the bike as 'not fit for the purpose purchased' under consumer protection laws... it was too late.
Got my refund a few days later, bought a better bike from a better company and have never set foot in their stores again.
