MY HAPPINESS OF 60GB IN THE DAY LIVED FOR ONLY 8 DAYS

my happiness was short lived. I received my supersonic on the 2 November and was activated on the 3 November on the 4 and 5 I was working 06h00 to 18h00 day of which I used the WIFI late Saturday and half day Sunday .I'm staying alone most of the time and my visitor has his Telkom Wi-Fi. I only have a cellphone with already downloaded apps on it and I have not changed my subscription to use them on my laptop or smart tv. I do have a laptop of which I use it mostly at night. Please make me understand how I CAN USE 60GB OF DATA IN 8 DAYS AND MOSTLY ON THE DAYS THAT IM HARDLY IN THE HOUSE .I HAVE ONLY DOWNLOADED VIRGIN ACTIVE APP AND PDF READER AND TODAY ITS FINISHED. If it was night I will but during the day I really don't understand
