I topped up $20 for my old phone and it automatically purchased Prepay carry over 19 plan. Right away, I didn't want to continue with this plan and changed my plan to my flex prepays plan and that happened to be another purchase of $20. However it seems like the data and mins purchased automatically beforehand is now just gone and I ended up purchasing $40 for a month just for nothing. I didn't expect my purchase would be automatic because it is my old phone and I'm hoping the double amount of money I ended up purchasing doesn't go to a waste. Please tell me what really happened to my plans and if the money I happened to purchase automatically can be cancelled.
