WHAT KIND OF SERVICE IS THIS?

My job requires late hours and I get home after 9pm at night. I arrived home tonight and the electricity had run out. I bought R100 on the app via Ozow and when the power did not switch on immediately, I proceeded to buy an additional R100 thinking there might be a minimum amount to upload after electricity had run out. Still no power. My landlord advised me to go to the apartment building's security to check my unit's switch on the DB board and it was turned on like all the other units, whose lights are on. I revisited the app and saw something interesting: office hours Mon-Fri, 08:00-20:00. By process of elimination I have thus concluded that my purchase will not he processed until tomorrow morning (after 08:00) and there is NO EMERGENCY HELPLINE FOR A COMPANY WHO SUPPLY WATER AND ELECTRICITY METERS; NETVENDOR. You cannot even call this a service, honestly.
