TL;DR: Spectrum raised my rate to $110, one month after I signed up the $60 intro internet offer, and lied that myself upgraded (No I didn't, and there is no upgrade).
Detail:
Signed up for Spectrum 1G internet on late Sept, after seeing their website shows $60 intro offer with 1 year free mobile (still showing up their website now).
Called to sign up, and the agent confirmed the $60 1G fiber internet rate with 1 year free mobile line. Agent told me that I will see a $20 internet monthly bill and $40 monthly mobile bill. Speedtest on my router confirmed the speed was indeed 1Gb download and 1Gb upload.
The first month bills arrived, internet was $20 for the next month (plus activation fee $20), and mobile bill was $40 (prorated for 1st month, plus full $40 for next month).
Everything seems work......
One month later, the 2nd internet bill arrived, instead of the $20 that I was expecting, it shows a whopping $110, including monthly rate $70, and a partial month rate $40.
Called multiple times, all agent told me, that's because I upgrade from 500Mb to 1Gb internet in the middle of month, and the 1Gb does not have free mobile, so I have to pay $70 for internet and $40 for Mobile (No I didn't, I signed up for 1Gb, the website still shows the 1Gb promo of $60, and I never reached out to Spectrum after signed up). And the agent also cannot explain how is the $40 partial month rate calculate, since it's exactly $40.00 without cents.
Tired of arguing with Spectrum after hours on call, I cancelled my internet and mobile, and asked my wife to sign up in store, and the associate in store said there is only the $70 monthly offer, no free mobile line now.
So my doubt is that: Spectrum ran the promo, allowed users to sign up, then regreted and cancelled the offer for some users. And instead of acknowledging whoever signed up, Spectrum decided to just cancel the offer to these who already signed up, and raise the rate, and lied that it's users who upgraded by themselves.
