Add-on purchased multiple times in error Hello,I wanted to purchase 1 x 6GB - 1 month add-on for £10. When trying to purchase it on the app, it gave me an error message saying "Oops... something went wrong. Please try again.". I checked my Home screen and the data remaining still showed what I previously had, so the purchase of additional 6GB clearly hadn't gone through. I therefore tried a couple more times, but kept getting the same error message. I thought maybe it wasn't working because it was on the app, so I went online on the website to try purchasing it on the website instead. To my horror, the home screen through the website showed that I had an extra 18GB of data on top of what I previously had. I don't need 18GB of extra data and I certainly did not intend to purchase 3 x 6GB - 1 month add-on, it was only because of the error message saying try again that made me click it two more times than I wanted. Just so you know the home screen on the app still shows the balance without the additio
