How Long Before A Wedding Are Room Blocks Supposed To Be Released?

I secured a block of rooms with the Comfort Inn in Waverly Iowa for my daughters wedding on October 24th, 2015. I called today, (Sept. 28th, 2015) to see if any guests had selected a room from the wedding block yet. The manager informed me that the rooms had been released on Sept. 10th. She further informed me that I had signed a contract that stated this, (which I'm sure I did) though I must have missed the part about that they would be releasing the rooms in Sept. OR I no doubt thought it said that the rooms would be released on OCT. 10th, not SEPT. 10th.Do you normally release blocked rooms for a wedding more than 6 weeks before the event? I have blocked rooms at other hotels and the release date was generally 2 weeks before the event. Most of our guests are just now looking into hotel arrangements.Isn't 6 weeks before the event awfully early?Additionally, I have now been on hold on the phone with your "customer support" line for 17 minutes without being helped by the way, prompting me to write this. I must say I am getting irritated and I am seriously considering cancelling the one reservation I do have at this hotel, in favor of finding a hotel with better customer service.
