Thanks so much for reaching out, sorry to see you are having such a weird issue!
When you look at your bill, did your credit card company reverse both payment charges or just one of the two?
Lauren asked a good question that will help us figure out what the next steps are to get your account handled. If you've already taken care of this, awesome! If you're still seeing a past due balance on your phone bill, please get back to us.
Good morning! Sorry to read about this billing snag -- I know it's been a few days since your post, how are things going? Were you able to see a single successful charge on your card now, or were both of them removed? Hoping that this has been ironed out, but please let us know if you're still looking for assistance!
