I love my bike but...

I love my bike, but the day it was delivered the box was damaged and my kickstand was bend 90 degree, unable to use at all. I contacted customer service and still today I didn’t receive the replacement. The gears, my husband work with bikes for 30 years, and they put a 6 gear in a 7 gear bike. I only have access to 1-6 or 2-7 which I let them know and they said that’s no a problem but it’s. The bike is precious and works great, I got tired of waiting for replacement and I’ve to purchase a kickstand... for the price I paid they should at least return some... but anyways.

It was never delivered. I ordered it for my son in Pennsylvania and it never arrived. I never received confirmation of delivery or even that the order was taken. I’d like to get this rectified thank you!
