Mweb speed

We have a contract with M Web for a year and two months. For the last two months we cannot do anything at all. From 25Mbps (fibre line) to 2Mbps drop on the upload speed. I am paying R500 per month to get irretated and furstrated. After many telephone calls to m web i still have the same problem. For a year on contract , no premblems. As soon as my contract were over, and went over to month to month, the throttling start. The service are terrable. When we phone they fix the problem. Just a few minutes after calling they throttled us again. My phone calls cost more than my premuim. I do not get any service from them at all. Paying every month for nothing. If i buy a bread for R15 I'm getting the whole bread not just two slices. Worst service ever and I'm going to warn everyone about the poor service of m web and going to stop paying and get another provider.
