Changed the number on my primary line about a month ago and now can't see both devices in my account though both are usable. Tried to use chat to get the issue fixed but they could see the devices but I couldn't get them to understand that I couldn't see them. Issue is, want to replace the line with a tablet on it to having a hotspot as I now live out in the country to where I don't have landline internet. Any advice on who I should try to get ahold of to try to get this straightened out. Tried to go the phone route and the person I talked to emulated the ones on chat and couldn't/didn't get the issue fixed. Tablet still works, I'm getting charged for it on my bill, but I cannot see it in my account to upgrade it to a hotspot or cancel the service and start a new line with the hotspot.
