I had TWC first before Earthlink. TWC gave me the modem. I switched to Earthlink after being with TWC for a year and a half. I only had a 6 month promo with TWC but they did not raise my rates to full rates until after a year and a half at which time I switched to Earthlink. As I stated previously, I switched to Earthlink via a Saveology(?) promo. I never had to give a modem back to TWC. Just used the one TWC gave me when I went to Earthlink. Things change and I switched to Earthlink over 6 months ago. This was all before TWC started instituting modem rental fees.
