All smiles when lots of money spent, but the worst after service possible!!!

I have spent a large sum of funds upon doing 2 bathrooms at bathroom bizarre. I've paid and arranged for delivery of all my goods, however they claimed to have had no stock or a certain basin and unit for my bathroom and the sales lady insisted it will fit in my vehicle. All well and done they brought it by their own terms to my car and loaded it, it so happened that we just opened the box and the basin has a huge chip on it claiming it had obviously been damaged in store or dropped or whatever the case may be. Bear in mind i didnt ask to take delivery of it and now apparently K.G from the Xavier branch states there is nothing she can do about it?? Why the hell would I pay for delivery fees if I have to take this damaged unit home without knowing and now they are unable to do anything about it?? The packer slides the box open with a pen he does not even lift the basin out to see if its damaged, he says "it's in a plastic its new" and I'm suppose to be like its brand new, thats not my job. Definitely not as a customer spending multiple of thousands of rands it store. I demand some feedback and a solution to this matter ASAP . No way in hell I'm going to leave this unsaid! I mean a basin well over R4000 that proved to be damaged needs to be replaced at the soonest.
