Upgraded to Premier service but still getting preferred speeds

Hello and thank you for reading.

I upgraded to Cox Premier from preferred yesterday 7/19. However, I am still getting preferred speeds.

After the Premier upgrade I am receiving the same 25 Mbps down (using either my router, or direct from my PC).

My modem is showing 4 bonded downstream and 2 bonded upstream.

I have checked all wire connections, cables, and performed several speed tests on various sites, but my download speed cannot achieve greater than 25Mbps.

I also emailed  cox.help@cox.com about this and included a link referencing related threads in this forum.

Any assistance solving this problem is greatly appreciated!
Thanks
