TDS didn't honor my pre-registration pricing

I know there has been lots of talk about experience with TDS so just wanted to make folks aware of an issue I dealt with today. Like many of you I was excited to get away from Spectrum and pre-registered with TDS last Spring. I signed up for 1G for life at 59.99 with the installation fee waived and one month free. Here is a summary of the past 13 months. We waited for TDS to "come to our neighborhood," then scheduled an installation date last fall. The crew showed up with the wrong equipment to bury the line, which I had arranged with customer support. They then sent two different crews out to flag out gas and water lines and then flag out a path for the fiber cable. Then crickets. More than 6 months passed, we called TDS in April to confirm when we could set up an installation. They stated that they couldn't come out to finish the job until spring (spring is a state of mind, I guess). Last week I finally got the notification that we could schedule an install, and I did. The crew who came out to dig for the install was kind and professional, as was the second crew that did the work to get the cable into the house.

This week, I received my bill. The bill is for 69.99 per month, and also includes the installation cost. No problem, I figured maybe there was a mix up since the process took over a year. I spent two hours on hold yesterday and three hours on the phone today trying to have TDS honor the price I agreed to. They consistently gaslit me and said my bill was correct. When I gave my transaction ID (from my order confirmation email, which proved I had signed up for the other price) they changed their tone and offered to either give me a 12 month $10 credit (doesn't sound like a price for life to me), or to "grandfather me in" to 59.99 per month IF I agreed to remove the one month free option. After spending hours arguing with different supervisors I finally chose the second option, only to learn that the "one month free" credit I would need to backpay would be $70, since that was what THEY had credited to my account, even though the one month credit I agreed to in my pre-registration was 59.99. So I'm paying $70 for my first month because they said so, even though I signed up with a first month free promo.

I know it isn't a huge difference, but the fact that they could add an arbitrary value to the "credit" to my account and force me to pay an amount I didn't agree to really makes me upset. What if they had chosen to credit me $100 and decided I now owed that? Ridiculous. The service has been good, and I'll keep them for now, but was really frustrated by them acting like providing me the price I signed up for was a special privilege. Keep your receipts!
