Did my money spell work or just a coincidence?

Two years ago, I had a spell cast online. It was only like $25, so I thought what the hell, Ill try it at least once. I waited and waited, but nothing happened. Then when I completely forgot about the spell I had some unaccounted money in my bank account. I always kept accurate records of my checking account and I had $850 and have no idea where it came from. I then checked my account online to see where this deposit came from and the wearied thing is their was no trace of this deposit anywhere. Did the spell cause the bank to make an error or just a coincidence. I then closed my bank account that week, so they wouldn't find out about it and of course they never did since my account was closed. If this is what witchcraft and spell casting is all about, then I'm all for it. I was actually thinking about going to the same spell caster that I did two years ago to purchase a love spell from them because I really really like this girl a lot and want her to fall in love with me. What are your thoughts.
