$28 bill suddenly $104-Quadrupled Overnight

My Mobile is already with xfinity, is $48/mo and is not free. I have only one line with unlimited data. I have been paying that since July 2023. 

I looked at all the options- I already have the xFi Complete installed in my home-not sure if it can be removed and that is an automatic $25 per month.

The tiers offered are 300mbps at $70/mo, 500mbps $79/mo (My current plan), 500mbps w/parental controls $85/mo and 1gig $100/mo.

Even if I switched to the lowest tier, it would be $90/mo. It is now 5X the price of all last year (10X the original price), as seen plainly in my bill summary below.

There is no deal I could find to make it less than $90.  It is hard to see this as anything other than a bait and switch. 

 I also work remotely occasionally and have had the internet crash in virtual court. To reliability work remotely while talking to the Judge, it would require me to get a higher speed than I have now. I stopped working from home on court days because my internet crashed while I was presenting to the judge in oral argument, which prejudiced my client.

I was not able to find any offer/deal visible to me that fit my needs.

Thank you for the information @user_60ek8r. The xFi complete is a older add-on that we offered that would provide unlimited data, but with the plans we have now unlimited data is included.

I have reached out to the support team. If they are unable to help, I will update this post for transparency.

So far, the support team has offered to only double the bill to $70, by giving me the lowest possible speed of 300mbps with the ability to watch NBC shows streaming on peacock tv for free.
