Express Pools do not value a contract

I had my pool installed more than a year ago and part of the contract was updated building plans arranged by the contractor. Today, 1year and 17 days later I still do not have my plans. Dispite numerous calls, messages and unfulfilled promises -still nothing. My calls are now being ignored and messages unanswered.i upheld my part of the contract, paid on time but Express Pools does not seems to value their contract or their customers
