Terrible Service, No connectivity for 3 DAYS

I have been unable to use the Internet for the third day now. On Saturday, it was due to alleged network connectivity. Yesterday it was because the sim card had to be rebooted. Then it worked for a short time. This morning, wouldn't work again. Rebooted the sim and reset router to default settings. A short time later, no intenet again. But it shows there's an active connection on their side, allegedly.<br> You best believe, come midnight on the 31st I will lose all unused data, despite the fact that the supplier can't deliver a basic service. I have been a loyal supporter for years, but this is beyond absurd. Am SO livid!!!
