RRPS tax receipts question

Hi,
- When I go to my bank to make a RRPS contribution depend on the type of the contribution sometimes I get the tax receipt and sometimes not.
- For monthly contributions the tax receipts are issued in the period Jan - March usually via post office
My questions: How to make sure not to miss any RRSP tax receipts and how to make sure the receipts are accurate? I mean easily, i.e., without too much effort if possible.
How do you normally check your tax receipts?
Thanks.
