Hey @Sally22
Welcome to the community and thanks for your post.
Sorry to hear that you've been having issues with your Tivo box over the last week.
I have been able to look into your account and can see that there is a congestion issue in your area that has been logged under reference F008756216 and has an estimated date and fix time of 26th Feb @ 1pm.
Are you having no service at all? The issues would cause issues with your services but still should be working but slower than usual. Please could you try a reboot of your box to see if this will help at all.
Regards
Steven_L
