Looking for a specific part that broke

I bought this machine a while back.
robotshop.com/ca/en/autopetfeeder-small.html

There is a metal cylinder that holds the motor’s output bar to the big white screw that feeds the food out.
That little metal cylinder has 4 holes on it where little metal pins go in to hold onto the motor and the white screw.

What broke is one of the little pins that go thru the cylinder.
The thing that broke is the little pin of metal that is passed thru the metal cylinder and that is bent on one side to not come out.

Is there a way i can get/buy that metal piece?
Should i try placing and bending that metal in place myself? or send it in for repair?
The rest seems fine, the motor is working, but i need that pin to hold the white big screw in place.

Thanks

Hi,

Please contact our support center directly with your invoice number and we should exchange it or repair it if it is still under the 5-year warranty.

Unfortunately, we do not sell this particular part.

Thanks!
