Nah, You're not loosing it, at least not yet!
That's not so bad, Hawky. A couple of months ago, I sent a check to the wrong company.

I've never done anything like that before. I didn't realize it until the company I should've sent the check to sent me an overdue bill. I'm never late with payments. In fact, I pay early. Then I realized what had happened. In my electronic bill pay, the companies are listed next to each other, and I was looking in the wrong place when I sent it. My bad. What p*ssed me off was that the wrong company cashed the check when I didn't owe them any money. I straightened it out, and they sent me a refund. I called the company I should've sent the check to and explained why I was "overdue". Thankfully, because they know I've never been late on a payment and have been doing business with them for a long time, they accepted my explanation NP.
So, I hope it makes you feel better to know that you're not the only one.
