About three weeks ago I received a letter dated XX/XX/XXXX from AFNI debt collection. Demanding payment to XXXX. This debt had been settled through XXXX XXXX XX/XX/XXXX.So I call AFNI at XX/XX/XXXX on XX/XX/XXXX and spoke with XXXX. He said he did not want to hear anything 'just get out you credit card and pay '. He refused to give me he last name. 

After XXXX settled this debt, XXXX XXXX XXXX XXXX XXXX Demanded payment on the same debt on XXXX. I brought the matter to your attention. And XXXX XXXX, XXXX investigated and apologized. Now here comes AFNI to collect on the same debt. Please help me.
