Incomplete after-sales service from delivery and installation individuals

I am writing this post on behalf of my mom who isn't as tech savvy. She has suffered poor after-sales service from the individuals who delivered her goods. She ordered 2 sleigh beds from the Decofurn in Springfield Park. The issue was discovered after the delivery folk had left. The beds are collapsing. The legs underneath supporting the bed fall out with very minimal movement by a person on top of bed, causing the structure to collapse. I have tried to assist her by checking if the legs are different lengths but are not. Upon further investigation, I discovered that there is a socket missing that is meant to keep the legs from falling. My mom is reticent to go back to the store to ask for assistance as she can no longer find the slip for the beds. I am writing this with the hope that someone can be dispatched from the Springfield Park store to come complete the installation of the beds as no one is sleeping on them because of safety concerns.
