Be cautious in your choice when installing a pool

They installed my fibreglass pool less than 2 years ago. After 9 months the pool sank and I contacted them and I was informed that it was normal even though the water level was obviously lower on one side. The pool shifted more with the storm in May 2019. The paving was ruined with massive cracks some of which appeared prior the storm and we filled them. I regret having paid so much money for this.
