When did you cast the spell? Magic can work fast, but it can also take time. It could work in the future.
But, WHY did you use this spell? Does it feel right, do you think that putting your paycheck and card on a pentagram will really work? Or you just found it somewhere and used?
If you wrote it yourself, did you take time to make sure it's a good spell or you rushed it without concentrating?
Honestly this sounds like it was put together in a rush and I think you should work on it a bit more.
Did you cast during the right moon phase?
There are just so many reasons why a spell would fail and it's not enough just to believe, you should work on your spell.
So if you failed - there could be many reasons for that and you should know why if you think about it.
But you maybe haven't failed, maybe it's just taking time.
