Is the ghosting of me justified?

Because of a renovation, I was a bit stressed and forgot a client's online appointment twice. But before the second appointment, I remembered it two hours before, but since I was already out in town running errands (for the renovation), I panicked and tried to reach the client. Yes, it was a mistake to try six times (at twenty-minute intervals), including sending him several messages. But he simply didn't respond or pick up. Finally, he did reply, two or three hours later. As an apology for the whole thing, I did him a free translation, worth about €50. It was about language lessons. Then we met again, and I gave him another 10 minutes for free. He seemed in a good mood. We arranged to meet again. Yes, and that was three weeks ago. 🤔 He's online, but yes, I'm probably dead to him 😅 Even though he was my client/student for a year and I was never late.
