Quality and Customer Service Disappointment

I recently bought a table set from Decofurn Centurion. Upon inspection by another party of the table 2 weeks later, I realized that there is a defect on one of the table tops that I had missed. Upon inspecting the pictures I took of the showroom set, I did indeed realize that I was sold a table with defects. Today, the top was taken back to the store on my behalf ,as I am far from the shop, with both the picture and receipt and was told by Ewan, store manager, that there is no returns after 5 days etc. I was called and the gentleman insisted that I spilled on the table and tried to remove the stain with something that created a bigger stain. I then explained that the type of defect the table had could not be from a stain and the gentleman then eluded that I tried s****ping of the table. He then said there is nothing he can do except raise it up, without giving a clear soltuion. This type of customer service is beyond a disgrace for the quality of product I received from a company I bought most of my furniture from. A total disappointment.
