Getting help by from Xfinity assistant and phone is impossible.

I will be switching to xfinity NOW internet and want to be sure that my mobile by the gig plan remains the same. I was told there would be no change but that I should notify the “mobile team”. Can someone verify this for me Thank you sorry to vent about support but it is horrible. Xfinity assistant just went in circles and I couldn’t get it to put me into chat and the phone call was useless, extremely hard to understand especially with all the loud voices in the background. Venting!!
