Should HOA have a TV/Cable package for all members?

I live in a HOA of 1662 units. TV service is provided via a bulk service agreement. 75% of owners pay more than subscribers who deal direct there are also service issues which has given rise to many complaints. I requested access to the Association's file and was given access to a file containing the contract but no correspondence. The Association maintains that there is no such correspondence. The dispute was mediated, the Association merely restated that there was no correspondence. The contract was incepted in 2008 for ten years during which time meetings have been held with the cable supplier - its difficult to believe there has been no correspondence no even confirming the date and time of meetings. What is the next step?
