In XXXX I found an unfamiliar XXXX Wireless account on my credit file, I contacted XXXX to discuss in further details but they stated by law they can no longer can discuss the account because it was sold. I contacted the company it was sold to - Jefferson Capital System - the company the debt was sold to and they forwarded me XXXX. On XXXX/XXXX/2015 I spoke with a rep from that collection agency ( working on behalf of Jefferson Capital System ). I 'm not sure what XXXX is charging me for. I had a phone with them but returned it in three days after signing up because I realized that I could not afford it. First XXXX XXXX XXXX said they have no details about this account. Jefferson Capital System did n't provide details but they are only responsible to collect payments. XXXX said they have no details and Jefferson Capital System directed me back XXXX. If no one can provide me details about this account and the charges, why am I responsible to make a payment? This is unfair and does n't make any sense to me.
