Dropped calls and still no caller ID

Ever since I upgraded my phone (iPhone 6, required a SIM swap) last year November I've been without caller ID. Messages to their support forums go unacknowledged or questions or complaints are marked as "answers" when they are not (I even had one of my own complaints marked as an answer to someones question, when it wasn't one).

When I call I get a robot directing me to download their app. I do so and there is no place to activate caller ID.

I'm told online to activate the caller ID service on the website. The entry under "My services" does not exist.

I'll get several "call back" notices, one every two minutes, but not a call.

I'm having calls dropped on the first ring, and I cannot tell who it was or return a call due to called ID not showing. I've checked that I don't have "Don't disturb" or "Silent" activated.

Their online billing indication is also messed up, it's apparently one or all of the following:

A) Unavailable (Website) B) R 0 (App) C) R 321 (Also website) D) R 418 (Call centre) E) All of the above? F) Guess.

It seems like every other month there is a new issue.
