Credit reporting or other personal consumer reports — National Credit Systems,Inc. (FL)

Account information incorrect. National Credit Systems has made allegations about this debt for {$6800.00}. My husband and I have communicated with them via U.S. certified mail ( XX/XX/2023 ) requesting additional information and have not received a response. We have waited 30 days, plus an additional 5 days to give ample time to allow them to do their due diligence. I have attached all correspondence and tracking information for the certified letter. We have an unsubstantiated debt being reported to the credit bureaus and this is concerning to me as a consumer.
