Bought airtime through cellphone banking app, amount was deducted twice

My query is still not sorted out. It’s been coming a long way... , queried it on 8 Jan 2018 (telephone call) and then on 2 Feb again (email), but no response.

I bought airtime for R110 on 21 Dec 2017. Standard Bank deducted R110 TWICE. I checked the airtime afterwards and it was indeed only R110 worth of airtime. I phoned Vodacom on the 8 Jan at 7:48 and they confirmed that. The consultant asked me take it up with Standard Bank, which I did. They also called Vodacom, and Vodacom told them that I received the airtime twice!!!

So, I really need to know what happened, please. Did or didn’t I buy 2 x R110’s worth of airtime? Can sometime go and look for the CORRECT answer? Or maybe provide me with a copy of the call I made to Vodacom on the 8th of Jan, so that I can forward it to Standard Bank? They said it will be sufficient to pay me back the R110.

I also logged a callback to Vodacom, which now, for more than a year, haven't been working!! It only worked the first time. When logging a callback the 2nd time you get a SMS saying "You already have a callback request pending. Only one request is permitted at a time. You will receive a call within 24 hours", doesn't matter if the consultant already phoned you back. It doesn't 'clear'. I have logged this error at least 3 times with Vodacom, even asked their IT department to call me so that I can explain, but nothing!!!!!

So there are 2 queries here, if you didn't catch it: 1. R110 deducted twice 2. Callback doesn't work, SMS doesn't make sense

I would LOVE feedback! Otherwise I will log it again and again and again...
