Timeout Question

[Teigan]

Coach of Team A calls a time out, he does not say whether he wants a 30 sec. or 65 sec., after I asked him what he wanted, and he didnt tell me (either intentionally or unintentionally ignored me), I charged him a 30 second timeout. I blew the whistle cause his team would not come out of the time out after the horns. He told me that he wanted a 65 second time out. I told him well you got charged for a short time out, and I put the ball at his team's disposal. I was then forced to call a 5 second throw in violation, and the other team came and took the ball, and scored. This coach was not to impressed, and voiced his displeasure, I informed him that he next time needs to be more clear in his request for a timeout. My question is: Did I handle this situation correctly?? (We use NCAA Men's Rules, if that makes a difference)
