how to leave a good customer service review?

I am a new customer to T-mobile as of mid Oct. 2023.  The entire experience so far has been terrible and continues.  It seems that the right hand does not communicate with the left hand.  It took three days to get my service up and working and I had to go to a store (had no phone service).  Then someone changed my plan without my authorization.  Then Apple promo did not work.  Each time I try to check on the status of a rebate it asked me to login at least 3 times.  I get so many insignificant emails from t-mobile even though I have unsubscribed.  Still waiting on switch and keep payment of my phone even though I submitted documentation.  Some reps are better than others, but overall the experience should not be this difficult.

cant answer the rebate delays but usually if if youre having network issues not long after changing carriers its due to the former carrier taking their time to let your number go..

if you started off fully fresh with a new number then thats all on TMO botching that one up. did they by chance give you a temp number for a few days at the beginning?
