Ad free netflix on stream saver

I have Xfinity now and Stream saver bundle (Netflix, Peacock and Appletv+) I was paying for ad free netflix but just recieved an email stating that I have been downgraded to Netflix with ads from Netflix. I call customer service at Xfinity and they told me to contact Netflix so I called them and they said only Xfinity can change it. I went to an Xfinity store and they said that Netflix no ads is not avaiable any more on streamsaver. Is this true? or can I still upgrade to no ads?
