This is odd - Maggie, the supervisor, had to call me at my Verizon wireless cell phone number, which she had in her records, but Jessica could not transfer me to Maggie because it was against company policy to do so.  Maggie informed me of everything in my bill - as if I could not read my bill.  But when I said that the agent that changed my plan did not explain that the charges for a "NEW PLAN" were not effective until the next month - even though they changed "THE PLAN" immediately, she informed me that I was lying.  What's more, is that the agent didn't tell me that the refunds would not be effective immediately - even though the "THE PLAN" was effectively immediately.
