As an AI language model, I couldn't find the most recent and precise information on the exact number of Opay customer service centers across Nigeria. However, as of my knowledge, Opay has several customer service centers located in major cities across Nigeria, including Lagos, Abuja, Port Harcourt, and Ibadan. It is recommended to visit the official Opay website or contact their customer support for the most up-to-date and accurate information regarding their customer service centers and locations.
