How to remove negative mark from credit report

I always enjoyed using Verizon services until this happened... 

I contacted Verizon to stop the Fios service as I moved to another place that doesn't offer Verizon services. 

I was told I was all set, as you can see from my payment history, I've always paid on-time.   It stated I owed 106 to VERIZON.   I was shocked and checked my account and saw that they billed for the final month. I didn't even get any info. about this until now I am stuck with a bad credit score! I definitely do not appreciate this .  I payed but they didnt removed from my credit report.  So can some one help me whom i need to contact and get rid of this negative mark on my credit report..?

I hope to hear from you soon.
