First Bill for new Internet Connection

[IMS25]

Hello:

I am trying to understand my first bill for a new internet home connection ($45 per month net of $30 credit for the first 12 months): 

Jan 25, 2021:  Order placed for a new connection

Jan 26, 2021:  Modem received

Feb 03, 2021:  Bill received for $63.68

I understand that there is a prorated amount included in the bill for the 5 days of Jan 2021 ($11.35 of other charges due to partial monthly charges) and an HST of $7.33.  However, I am unable to work my way towards the amount of the bill.  How has this prorata been calculated? No per day calculation leads me to an amount of $11.35 for 5 days.  Any guidance would be much appreciated. Thanks.

Hello @IMS25,

Fido apply credits only once per bill so you would have been billed at full rate for the first 5 days and for the following month then the credit would be applied. The credit would never exceed $30 as you mentioned per bill.
