Slow internet speed

We're still struggling with slow speeds since 9th November 2025 till today 2nd January 2026.... Especially from 7am until 00:00am when I call I'm being told that it is tower latency, but there's no progress whatsoever to resolve the matter... We only have one 5G tower at Dikgakologo primary school against more than 100 devices connected to it obviously it's not going to operate efficiently... Please upgrade your infrastructure so that everyone can happy with consistent speeds
