Plan upgrade - currently advertised pricing

I'm an existing Xfinity 2 Gig customer paying $119/month, with recurring $30 data overages.

I've already spoken with your retention department, which offered me a five-year price guarantee at $135/month. They also suggested downgrading to 1 Gig for $95/month, which I'm not interested in.

Comcast publicly advertised its 2 Gig five-year plan at $115/month, including unlimited data and equipment.

I'm asking for an account-specific review to see whether you can match that $115 rate while preserving my 2 Gig service.

I've also experienced intermittent performance issues and would appreciate a technical review of my connection.

I'd like to remain with Xfinity, but $135/month is difficult to justify given the publicly advertised pricing.
