CELL C DATA DOES NOT LAST

Hi<br> <br> When I first joined Cell C and took up an internet package 3GB per month, my data would last me a month. Now it doesn't last at all. I can connect to the internet and go on just Google for 5 minutes and 100mb and even more gets used up. All my automatic updates are turned off.<br> <br> Please advise whats going on Cell C? If this continues then I am going to find another internet service provider.<br> <br>
