Terrible customer service

Cybersmart must be the worst ISP I have dealt with. I requested a line speed increase on 17 August 2020. I have emailed, I have spoken to support numerous times. I keep getting promised that the line speed will be increased and it will take 48 hours. It is now 4 September and still no line speed increase.

I can't speak to any managers and no one ever gets back to me. If they can't do it they must just tell me.
