Bought R100 electricity & No units on my receipt. Meter ***

Good day, on 1st July I bought R100 electricity at 18h24pm pick and pay Sky City Mall Alberton and I was given my electricity with no units on, meter number *** I called call centre this morning the 2nd needed someone to explain why I have no units on my receipt I was told that I must visit the nearest energy branch for their technical glitches which will cost me a lot of money, can someone call me with my units as this is your problem and we should have received the memo to to purchase electricity yesterday. This is Really annoying and unprofessional. Whole company is making their problems customers problems. Get this sorted as I need my electricity back.
