PATHETIC SERVICE_STILL WAITING ON PREPAID ELECTRICITY PURCHASED 2 WEEKS AGO

It is absolutely unforgiving how pathetic their services are. I go back to my previous review where I complained about their services. To date, I have still not received the R200 prepaid electricity purchased on 07/10/2019 via the Nedbank app. Receiving a call apologizing and informing me that it has been escalated for investigation does not resolve my problem - where is my prepaid electricity voucher? How long does it take to resolve as it is now over two weeks?
