Unprofessional Service - Angry Customer

I recently purchased a number of items at Tile Africa Alberton, My experience was pleasant until I started having issues with few of the items , The current being that the shower which I purchased seems to have dents and sc**** marks on the panel, I contacted the sales person who assisted me and he advised that I should send pics of the panel and they will contact the supplier and they will send some1 out to come and make the necessary assessments in order to resolve the problem, when I followed up I was advised that the suppliers had provided feedback that they are not liable and that the goods are packaged without damage indirectly stating that the problem was caused by me and they could assist in providing me with a replacement panel at an additional cost, This response made me furious as it indicates they do not want to take ownership and are simply unprofessional. What I have noticed with some of the other products I had an issue with was that the boxes are tattered as a result of sitting in the Tile Africa warehouse for to long, so my question is if something gets damaged in the warehouse and then gets sold to the customer who is then liable? I say this because in my previous 2 issues I had parts missing in a toilet and then missing tiles in boxes, (These 2 issues have however been resolved) However I make mention of this is to indicate that factory faults and issues with stock is common, Its up to the Dealer/Supplier to take ownership and resolve as the customer is entitled to the product in the agreement in which it was purchased.
