No assistant for missing data

Hi 1st of Aug received my rutter data which was fine. To my surprise coming back from work around 5pm , 9Gig was missing for the night data which i fail to understand as my phone was the only one connect and didn't need all that data. As I monitored my usage coming back from work that day, I lost like 5Gig of data inlike 3 hours which I don't understand how. That continued up to today. To this day with the data i used and of the missing data it says I've used 53Gig in just 10 days which I couldn't. called the call center after some time of struggling to get through, I still wait to be assisted with my missing data. Can you please explain to me what happened there and in any case of a system glitch please refund my data. My number is ********** .
