I also received this letter but for Owen J Roberts SD/East Coventry Twp. I contacted them and they said it was most likely a mistake but they'd let me know. Now one year later I hear from them and its exactly 1/2 the amount they first sent? what are the odds it would be exactly 1/2? Plus they added in $35 in random "fees" and $18.56 in interest and penalty? For what? They have not given proof that I didn't pay what I did. I reviewed it and found that I DID pay what I was supposed to? How many people get this and just pay what they ask for? Wish I knew who exactly to contact about it. Wanted to leave this here in case others also google looking to see...
