What should I say?

My long distance boyfriend is great, but he doesn’t call me. Hedoes text everyday but I think calling is more personal. I called him and he didn’t pick up and I texted that I was just calling to say hi, and said he was working at the time…but never called back. This bother me so I mentioned he never calls and he said he would try sometime this week to call. Which made me angry because I don’t understand why he has to wait for a day this week instead of just calling today. I’m angry and I don’t know what to say
