I was on a monthly plan at £ 19.68 a month. My billing period is 21th on each month to 20th of the next month. Last charge was for the period 21/10-20/11.
On 4/12 I moved to a new plan, at £36 a month.
Hence billing should have been something along these lines:
- from 21/11 to 4/12 at £19.68, hence ~13 days out of 30= 13/30 * £19.68 = ~£8.50
plus
- from 21/11 to 4/12 at £36, hence ~17 days out of 30= 17/30 * £36 = ~£20.40
For a total of ~ £29
Instead I am being charged around £45, quoting £36 plus some adjustments from the previous account.
Clearly if my billing window remains the same (so next time 20/12), I should only incur in part of the £36 this month (which would instead cover 4/12/2018 to 4/1/2019).
Can someone from Vodafone look into this for me?
