Pathetic customer service - cannot get line activated

Been trying to get my fibre line activated since last week Monday (1 week ago), changeover order was booked 1.5 months ago. I've called their handling agent New Planet Group/New Planet Telecoms about 40 times already in the last week. Half of their call centre selection numbers don't exist or never get answered, I've left at least 5 messages, nobody calls back and escalations have no effect. Absolutely pathetic.
