On 2013, I ended my service with XXXX and paid the full amount. After the service was terminated, XXXX charged me for {$81.00} for the next month 's cycle which was a mistake on their part. 

I disputed this collection on XXXX and it was removed from my account increasing my credit score. 

Please assist with this issue I am having. I 'd like to keep a clean credit and I have always been diligent with my payments. I 'd be happy to provide more information. Thank you!
