Empty promises from game store that they will fix the gazebo

We bought gazebo on Monday of the week, only opened it on Friday to use it of the same week,it was blewed by the wind and the leg broke and we took it to the store and they promised to fixed it for us, every week they say the will call us to bring it the following day and they never did, I have evidence of our conversation with the manager, I’m so disappointed with their service, does it mean we must buy the new one?when the one we bought was not even 7days bought?
