Poor performance

I pay for 15mbps, I get 10. I log support tickets (15 in total), I don't get a reply. My router gets restarted by an "admin" whenever Sonic Telecoms deems fit, without notifying me (while I'm in the middle of work, dropping vpn connections etc) Little to no client communication - you get notified via sms AFTER work has already commenced/routers have been restarted.

Sonic Telecoms, the client experience I have of late is not good. I am looking at alternatives.
