Low quality products

Bought a 5 piece patio set and it started rusting, had to wait a long time for someone to come collect it and finally it was replaced. I decided not to unpack it until i finished relocating to a new home. The replacement proved to be an even bigger disappoinment, low quality products: chairs dont balance and neither does the table. 2nd complaint and response was 2 days later... now its been another 2 days and still nothing. Maybe i should get my lawyer involved...
