Promo ended and the new price is too high for my budget

I noticed my promo rate ended and my bill just jumped by $30 this month for my 500 Mbps internet plan which doesn’t fit my budget anymore. I wanted to see if there are any current promotions available to bring my bill back down to what it was; otherwise I’m going to need to schedule a cancellation date so I can switch to AT&T fiber for $50/month.
