He threw away cot bed with mattress

My husband never listen to me. Any time I ask him to do something he always do it wrong or he do not do it at all. I am starting getting enough of him. He is so annoying. Right now we are renovating a room of our daughter and we are getting rid of old furniture and we are trying to refresh this place. Our daughter will be six next month and since the day she was born the room was not renovated. We need to buy her new bed because she cannot sleep anymore in her cot bed anymore. She is just to big for it. I asked my husband to throw away the cot bed but to leave the mattress because I promised my sister that I will give it to her. She want to have a spare one in case her son will damage the one that he is sleeping on. Anyway my husband had to throw away only the cot bed without the mattress. When I was back from work I noticed that cot bed mattress had disappeared. When I asked my husband where is the mattress he calmly said that he threw it away with the cot bed. He said that I wanted from him to throw away the cot bed with the mattress. I thought then that I will kill him I was so mad at him. Additionally I did not know what should I tell to my sister who was waiting for the mattress. Of course my husband do not see any problem. He claims that if my sister want a mattress she should buy one.
