I moved to a new apartment. I called time warner cable to cancel my old account because I didn't know when I would be able to turn it back on. I called jose from a flyer that installs services for Time Warner Cable. He sent someone out to install internet and cable services. I gave my old modem to the Agent to install and with out me knowing, he took my old modem and installed a new modem. The Agent didn't add the old modem into their system so that Time Warner cable would be able to see that it was returned. Months later I recieve a collection notice with out any notices from Time Warner. I called customer services four different times and no one hepled me. I even asked to speak to a manager, he wasn't able to do anything about this situation, to make things worse he started to argue with me as if I stole the modem. This whole situation caused my credit score to be very low. I was planning on buying a home that I put an offer on. There is no way I can buy it. I don't know what to do.
