Horrible customer service

Been with them for close to 3/4 years now without any issues, all of a sudden last year (2024) around October our internet speed has decreased to the point that we can barely access the site to do a speed test on it. My husband has called their call centre more than once and they still have not resolved anything. I went the alternative route of communicating with them on Facebook to try and aside from the same automated responses they have been absolutely no help. After bringing it up with them that we've been paying for a service that they have not been providing they said that their usage threshold is 1gb a day. In other words if you use more than 1gb of data a day according to them they've provided the service. Yet we pay for uncapped 10mb line and we hardly receive even a 1mb of speed. Even now late at night I had to revert to mobile data just to be able to access my browser. We can hardly to something as simple as send whatsapp messages. Their staff is incredibly *********** and unhelpful. Even their socials team via Facebook messenger has been of no help. Wouldn't recommend their services to anyone, you won't get what they promise you and they will not be able to assist you when you have probems.
