Poor quality product

We hired Dani as our decorator, she recommended an upholsterer to make armchairs. We were surprised at the cost of the armchairs R8370.45, Dani assured us the quality and workmanship of upholsterer was far superior to anything else we would find and they came with a life time guarantee. We were overseas so Dani handled design and chose a fabric on our behalf. Dani invoiced us and we paid her a deposit and then the final amount before the chairs were delivered. We queried paying the final amount before actually seeing the chairs, Dani assured us that she had signed them off at the factory and was happy with them. On delivery, Dani was with us, she was unhappy with the chairs, despite having signed them off at the factory before delivery. The arms were uneven, the upholstering had not been done properly, the fabric was pulling at all the seams and the legs were uneven. We have since sent the chairs back twice over the last three months and they are still not right and the fabric is damaged. Dani will not reply to our messages and is refusing to do anything to help us, the manufacturer Bellacraft, is saying that it is Dani's fault as she chose the fabric and she must solve the issue
