Pool Renovations

I signed a contract with PP in August 21 to re-marbelite my pool which they did thent. Since then the marbelite has been constantly coming off blocking my hoses and the pool cleaner which has caused me to clean this equipment 4 times for it to operate properly. The clogging up of my filter sand newly inserted after the marbelite was completed, still has to be assessed. Despite several phone calls & msgs to the owner, there has been no meaningful response or commitment to resolve the problem by a certain date,
