Did God call Moses three times, or did the story repeat itself three times, and by which of the mentioned expressions?

The repetition of a single story in the Holy Quran with diverse features, contexts, and styles demonstrates the eloquence of the Quran and presents a challenge to the disbelievers of the Arabs, showcasing the Quran's miraculous nature. The story of Moses and the Call was not repeated; rather, it occurred once. However, the Quran mentions in each Surah an aspect of what happened and what Allah revealed to Moses, and there is no contradiction between the Surahs.
