Spark - 9.4 / 12.7

Nothing wrong with the actual service itself, speed well within advertised ranges, outages are very rare.

But on the rare occasion an outage does occur, getting in touch with their customer service is a PITA. Extremely long hold times so don't even bother ringing them, and their chat service via their app is pretty janky - they don't use push notifications, so you wouldn't know when an agent has replied to you, unless you're glued to your phone, kept your screen alive and dropped all your work. Better to use the chat feature on their website via a PC, IMO.

Their other contact options are to use either Zuckerberg's data harvesting apps, or a walled-garden fruity messenger. Why can't they just use Signal (or Telegram), like civilized people?
