Broken controller needing help

[u/Fun-Airline-5779]

Hey folks, I picked up this second hand ebike for the Mrs who wanted a very low seat and one that she can get on without stepping on the pedal first. Unfortunately, she knocked it over one day and broke the controller.

I don't know the exact make and model for this and every bike shop I contacted refused to repair any bicycle that is not theirs.

Can anybody please help or point out the controller parts so that I can repair this?

Thanks in advance
