Mattress Firm review: manager choi young

Bought a serta motion I series and was delivered and Installed on 10/12/2019. Was missing connecting straps that keeps bed from coming apart. Saw manager and explained to him it was missing and he told me I didn't need it and tried to tell me it was an option. Was very rude and kept giving me the runaround. Finally called Serta and there sending me the connecting straps.
