I had a postpaid account with one phone and two tablets, but I called to cancel everything around February 7th.
I checked my account and it still shows two of the three devices as active. I made a follow up phone call on the 9th and they said it should automatically be corrected after a day or so, but I just checked and it still shows two devices still active.
How do I confirm that my plan was actually cancelled on the 7th? I don't have the sims anymore, so I can't pop them in to verify.
