Charged twice!

I'm frustrated right now because we were charged twice for a major purchase we made not too long ago. Unfortunately, it's going to take a couple of weeks to sort it out, leaving our bank account a bit parched and an unwanted balance on our credit card.

Here's what happened: We decided to renew our contract with our pest control company. Pests are a major issue here in the South, and I don't want to worry about critters crawling around/eating our house, so part of our budget includes regular pest control service. Last year, we paid one fee to cover 12 months. This year, when we renewed, we asked if we could get a discount by renewing for 24 months. The company agreed and charged our credit card the agreed-upon amount. We paid it off. All set, no problem.

Two weeks later, they randomly charged our card again for the same amount! Being sleep-deprived parents who simply want to keep on top of their credit card expenses, we paid it...before realizing a short time later what had happened.

Long story short, the pest control company can't just undo the extra charge (because we already paid it), and it's going to take them two weeks to get us a check to reimburse us. I am not happy. We should have taken better care to identify the double charge in the first place, and we shouldn't have paid it - but it bothers me that these people were so lax in their accounting that they made the mistake (a financially big one, too - two years of pest control isn't inexpensive, at least not to us). 

Plus, we're paying for the car repair we needed last week.

When it rains, it pours. Again, this is why we have the emergency fund, but it bothers me to dip into it for something so unnecessary.
