Plan jumped from $70 to $129

Well, it’s finally happened to me: after seeing price jumps from $50 to $70 to $90/month, my bill just leapt to $119 (after autopay credit).

I was about to switch both my internet and cell lines over to T-Mobile for their $35/year with 5 year price lock guarantee, when I saw Xfinity advertising a $50/month 1 gig option with that same 5 year price lock for new customers on their website.

Anyone have any tips on how to transition over to something like this? Xfinity’s phone support was no help.
