I believe I have been over charged this month. And my data has been incorrectly calculated. I usually have 50gb roll over from the previous month which is on my billing letter plus the 50gb I have and for some reason my app says I have used 100gb in 2 weeks which has never happened before as I usually have a large roll over from the previous months. My typical usage has not changed this month so I don’t understand where this loss of data came from. I have been charged an extra £10 because of this.

A similar thing happened to me around 8 months ago where I contacted your team again and they rectified the issue.
