Question about Net10 auto refill

[gale65]

Can auto refill be canceled on the Net10 site? I'm super unhappy with straight talk right now. Even though I topped up with phone cards, they still charged my credit card a full month before my service end date. All I can find is complaints about their customer service so I will give them a day to fix this, but if they don't, I think I will cancel the credit card I am using there and let my service run out and switch. I just don't want the same problem with another company.
