I got message said will not charge for the day April 19 without wireless service, however I just received new bill today for April 25-may 24, I didn't see any credit applied to my account.
it is very small amount for 1 day but should honor what Fido talked to public or customers
thanks god their home internet working that day, otherwise I had lost contact totally April 19
From what I understand, the credit should appear on your bill dated on or after May 1st.

Since your most recent bill is April 24, I think you should receive the credit on your next bill.
Hope this helps 😀
