Telkom night data only used when restarting your router after 00:00 at night.

Why do you have to restart your LTE router after 00:00 (24h00) to switch to the night data? I have lost multiple months of night data because nowhere they stipulate this primitive process to follow in order to use the data YOU paid for. Since the data you paid for just disappears and they not providing any indication of how to use it I would like to take legal actions against this very primitive and unsatisfying service provider. As a user I don't expect to have to restart my router EVER, especially while I'm supposed to be sleeping in order to get up to go to work early in the morning.
