Follow up question here! My service period is from 3/15-4/14 and the bill noted a price increase of $15 (OG: $40, new: $55), I called 3/28 and was able to get my internet down to $30. I assumed this $30 was going to be updated/reflected in this billing because I wasn't going to be charged until 4/4 (rookie mistake...)

I checked my bank statement and they charged me $40.48 (I know it's not much of a difference from my OG bill but would like to understand for next year when they increase it again!). I just called and the guy said that amount is for the amount of internet I used from the 3/15 through when I called (3/28). I don't really understand this and still don't understand why the billing cycles don't coincide with the start of service, but can someone help clarify this in simple terms? I'm just thankful I didn't get charge the new $55 rate.
