Internet disconnection

I made a payment today 2024-03-29 at 14:19,when I got home my internet connection was disconnected, it is the last day of making payments, why must they disconnect my services at 16:00,rather than 23:59?i made a payment, they must not make my problem theirs! If the payment don't reach them on time, i made a payment, I expect to be serviced as I made a payment, they must improve their payment services, as this is bringing inconvenience to me as a customer!
