Hi, Yes, you can use these two interchangeably. There is a slight difference in meaning: told ME - this sentence informs you that it is you, whom he wanted to hear what he had to say said - you have no information about who heard what he had said - he simply said something and it does not matter to whom it was said So, the difference lies in specifying the person / people who are told something. You say something (in general), or you tell SOMEBODY something.
