請問你點解199日計一次水費呢?
我剛到,Southern water幫我計direct debit :
Thank you. Just done a quick calculation of your payments. Option 1 the payment would be £40.89 for 10 installments until the next periodic bill. (09.08.2023)
For option 2 the payment would be £38.72 for 22 installments until the 2nd periodic bill.
