Worst online shopping experience

I bought two mayfair glass table lamps copper 40x25cm and one arrived broken in pieces because of negligence when packaging. reported the lamp & was Wesley had said he would get back to me till day. I then made a follow up and the lamp was said to be out of stock, requested that they should halt the refund. a week later, the lamp is back instock and have requested a replacement. I was then attended by Pearl, who is the BEST sales agent I have dealt with however sense that she too has limitation to these things.

the warehouse is now the issue and they wont replace my lamp, don't know what to do, I am frustrated.

Again my account card wont buy online and .
