Contour box slow to record or won't record or cancels my recordings on its own. Freezes.

             Contour box slow to record or won't record or cancels my recordings on its own. I just had COX TECH CERTIFY MY HOUSE WITH MULTIPLE TESTING on 11/10/2020. Everything including the Contour TV Cable box checked out good. This has gone on since January 2020. I had 7 boxes in 6 months. Sign up to record 6 shows at once. I only have 1 tv.  After a I delete a program. I have to wait 5 minutes to be able to record. This is my 6th box in 7 months. The first box lasted almost 2 years. 6 contour boxes since March 2020. June and July 2020 2 bucket truck Cox techs said there is an ongoing problem in Atlanta. I'm paying for a service that works well half the time. They have been upgrading services around here for severals months now so I get lots of slow downs or no services. I'm sick of calling the Cox Tech Dept about these on going issues.
