I moved our 2 numbers over to 2deg, but the reception around home and around Waiheke was.... well, unusable at best. So I've moved back to Spark.
I recall from when I signed up that there is a 2 week period from signing up where you cancel without paying, but I can't find reference to it.
Anyone know if this is the case? (I'll call customer service about it tomorrow too). If it helps, one connection is prepaid, so nothing to do on that, and the other is sim only, no contract, with the family sharing thing.
