Over a month and internet still not working

We starting reporting intermittent internet services over a month ago.We were not given a reference number from the beginning and was continuously told that the line was rebooted but within a few seconds it would go offline.The first ref number we were given was 875crk020316. Since then we have called in numerous times, emailed the complaints bureau and the escalations department. We have been sent a message saying a technician has been to fix the problem and can we rate the service.....what service.....every few seconds the wifi goes offline. This is no longer acceptable. If we missed a payment you would be quick to cut our service but its fine for you to ignore our problem....fed up!
