Electricity

I purchased a pre paid electricity of R200 on 20 June it gave an error I waited while the app was running and press send. Capitec took an additional R200 from my account which incurs bank charges. I called in and was refunded the 1 R200 I asked the consultant to tell me what the issue is and for my other R200 she then gave me a voucher number which I trusted was of the same value.I used the voucher only to find the value was R100. This had caused such an inconvenience Capitec is pathetic because she told me there an issue with the app. When I called back I was told I must call the municipality I don't have time for ******* I want my R100 voucher back, they can't even show me proof of the value only the voucher number. This even caused my geyser to break as the electricity wasn't sufficient. CAPITEC IS PATHETIC
