No, I haven't called in yet. Past experience has taught me to not trust what the CSRs say. So, I thought you, as a more reliable and trustworthy source, might have some inside info.
I'm always skeptical about accepting any "goodwill" offers from companies these days, because it seems like there is always some kind of fine print that a person misses.
Even though a modem upgrade shouldn't change my grandfathered tier and result in me having caps, there may be some fine print with this offer somewhere that says something to that affect.
If I decide I want a new shinny modem, then I may just go buy my own anyway. That way I can get rid of the rental fee. I assume Marshall, IL has DOCSIS 3 capability, correct?
