Damaged and dysfunctional bedframe

Hi there, The service offered when purchasing was actually really good. However, upon assembly, the bed frame is damaged, and the parts don't fit and is either to short or to thick to fit, meaning the bed will not work in the condition meant with the parts that I have, actually its completely impossible to assemble. Its a big inconvenience and I don't yet know how it will be corrected. I am quite disappointed. Do you not have quality control measures in place? Thank you
