Damaged goods

We bought the contessa dinning room set at morkels on the 8th of January 2015, The goods were delivered incomplete and not on good condition, and we reported the matter at the store and after two months they came and exchange two chairs' and after another week they came and deliver the dresser that was not delivered before' and it was also not in a good condition. We went back to the store and lay a complain, towards the end of March they came and exchanged the dresser. On the second week of April they came to collect the side board without replacement, we then go back to the store and the manager promised to make a follow up with the ware house but till today nothing is happening.We are tired about issue we need help.
