Work tried to call / text me way earlier on my off day to come in but I just woke up, what do I say?

My job tried to call me around 8 am 3 times and texted me asking to come in because there were alot of call offs. The problem is, I was up all night playing video games and I just woke up at 5 pm. I don't want them to think I was ignoring them, but I also don't want to tell the truth that I stay up til 6 am playing video games on my day off and wake up at like 5 pm lol. What do I say?
