Overcharged

September 27 2021 I ran out of data and paid R600 for an additional 100Gb which was immediately debited from my account and paid to Supersonic. Now come 1st of October instead of debiting R598.99 for my new month they have added the R600 which I already paid and took R1198.99 from my account. My statement does not show this and obviously they can't see it either because they can only see the same statement I am looking at. My statement shows that R600 was paid on the 27th and that they initiated billing for R598.99 on the 1st but my bank account shows that R600 was paid to them on the 27th and R1198.99 was paid to them on the 1st, no R598.99 payment. After an hour of listening to the same music I finally got through to someone who created a case for me, let's see how long it takes to get resolved, if ever. The problem now of course is that even if it is resolved, this could happen again and again if I have to top up.
