Our Technical Support is still available 24/7, we do hear this happening on occasion and it can be a few things - an error within our IVR, human error when selecting the options on the IVR or there is an issue with the billing on your account and it automatically gets routed to our billing department which doesn't operate 24 hours.
Hope that helps a bit and I would suggest trying again today to reach us.
This problem seems to come up every few months in the Community
When an issue like this happens on an account after hours, is there a way for MTS's IVR programming to offer an after hours announcement saying something like
"You will be unable to access Tech Services due to a problem with your account. please call back during normal business hours for assistance" and then then terminate the call
Doing this instead of a cold transfer to the customer accounts number and the customer getting the department closed announcement might be a little more informative for the customer.
