I think it would be wise to talk to them openly. Especially be open about the things you like and dislike so they don't get you a gift you don't want in the future. I don't mean just once. I mean in general. Communicate with people. Tell them about yourself. Listen to what they tell you. The problem is not you or them, it's communication. Another suggestion for the future is to make a big wishlist for your birthday or Christmas that hopefully people use as a guide when buying a gift.
