renewal

My internet plan is coming up for renewal (Connect More plan at 400 mbps).  Online there is an internet offer for $40/month (300 mbps) with unlimited data, includes modem, price good for 5 years, with no contract.  Just spoke with an xfinity rep who told me that the exact same plan would cost me $65/month since I've been a long-term, loyal customer.  I can only get the $40 rate if I cancel my current service for 90 days.  Then was told that I would lose my "loyalty" benefits (10+ years with xfinity) if I decided to cancel.  How is it a loyalty benefit to pay $25 more each month as a long-term customer???  Probably will switch to 5G mobile internet but checking to see if anyone is getting a better offer through xfinity internet.
