My family and I have had very spotty service for 3 days now. We can only hear bits and pieces of our words to each other. Are anyone who calls us or vice versa. I called t mobile and was told there was a ticket for this to be fixed and it could take seventy two hours. I am not sure when the seventy two hours began but for us it has been more than the seventy two hours. My daughters are out of town and it is very frustrating that I cannot talk to them. No talk tother business correspondence. That we need to speak on the phone too. Texting works fine. But voice calling does not. I have tried all of the troubleshooting that has been advised from shutting down the phone rebooting restarting changing my network settings to LTE. Instead of five g and everything else that was recommended to try. I just would like an answer as to when I can expect this to work. I also want to confirm that you in fact know about this problem and do have it in progress to be fixed. I know I was told from the local T-Mobile store that there was a ticket in for it to be repaired but I don't see any improvement. Whatsoever yet. Thank you so much.
