Adult Scooter - needs repair (Hammersmith)

https://euroskateshop.uk/story-70-s-foldable-commuter-scooter.html?2=6115189

I bought this scooter months ago but only just opened it and there is a manufacturing fault in one of the handlebars. It is flattened and will not slide in to its spot (see pictures). Customer service for this company is appalling so I'm giving up and giving away. I got this when on sale but is now at full price. Hope someone will have the tools and ability to reshape the handlebar and use the scooter.
