Upgraded for 1 month for Kids Christmas Specials, can't downgrade now.

I had called when my promotion ran out of $79.99 for Standard+ and I was told they could honor that price for another year, this was around end of November, early December.  My kids were asking for the Christmas Specials that only play on Disney Junior channel which I didn't get on Standard + so I called and the woman said I could upgrade to Select+ for 99.99, it being very clear that after about a month I was going to call to go back to Standard + because I can't afford that, I’m a single mom and daycare for 2 children is very expensive not to mention COVID is so bad and I have to work from home, I have to pay for people to come watch my kids because daycare is not safe but I still have to pay to hold their spot.  I called today and was told nothing is available at Standard+ for $79.99, so my option now is to start looking at other cable options for less because your prices are extremely high.  Very disappointing because if I had known I couldn’t go back to my previous package, I would have not done this for my kids.  Was just trying to do something nice for them since they can’t see their friends and family and stuck in the house all the time, and now my cable package is outside my budget of what I can afford.  I guess the jokes on me.
