Also I bought fully a Samsung Galaxy A52 5G and T-mobile told me they cannot DEVICE UNLOCK

I need to utilize an international sim when travelling and my phone according to T-Mobile meets the criteria but despite many, many calls, and chats (the chats never work even with a live agent and get hung up) I have not been able to get my phone unlocked.  The telephone agent said they were putting in a "file" over a week ago which would generate my unlock within 72 hours but this never happened so the latest agent I talked to yesterday agreed that it could be unlocked (meets the criteria) but could only put in another "file"/"request" which he was going to escalate and it would be done in 72 hours!!!  We will see.  The previous request was there for him to see so why did it not happen?  He said it was another department which did this but could not connect me to them! This all just sounds like an avoidance/run-around by T-Mobile!  Additionally, he could not tell me what the next step would be as far as actually unlocking it despite knowing my phone details - i.e. whether they would send me a note or message with further instructions or whether it would just be unlocked remotely.  This is terrible service from what used to be a reliable and reputable company but it seems since the merger with Sprint that it has gone all to hell!  Hopefully, after the next 72 hours this will this time all be rectified.  I too have mentioned to them that I will approach the FCC if they refuse to do what they say they will this time!  Hopefully I won't have to play that card and they will just do what they say they will!
