Pathetic service from Unipin SMS and email contact

I bought R1 100 of Unipin electricity and when I attempted to load it last night at 20:00, I got an error message about "meter not being registered". This is despite using the same meter for the last 5 years.

I sent an SMS to the number on the slip but 17 hours later there's still no response, despite claims that this is 24/7 service.

I want to get my electricity but there's no number for Unipin or response to my emails; PATHETIC service!!!
