Hello @liujianyuas,
If you move to a new provider, it sounds like you received your final invoice from Fido. If you log into your account on fido.ca and then click on print or save PDF under View Your bill, you will get a breakdown of all the changes.
Since we are normally billed a month in advance, it is usual to see a credit if you cancel/move in the middle of your billing cycle. If you have a credit, Fido would issue a cheque and mail it to the last address on file it typically takes about 6 weeks for you to receive it but if you made your payment by credit card you can call customer service and request the amount be put back to the card but you have to make the request before the cheque is issue.
If you still do not understand the invoice, then you would need to contact customer service directly, and they will be able to better assist you.
