NETWORK COVERAGE IS TERRIBLE

I have business deal with Telkom my data is available from 00:00 to 19:00pm it's business hours but network is always and forever available. I live in Pietersrkaal A Mpumalanga 0460. Very disappointed. please fix network coverage at Pietersrkaal A Mpumalanga 0460. I know i am just writing to this platform but ya'll don't care.
