Samsung S22 plus does not conform to specifications

I logged a service call on 21 Dec 22 for my S22+ as my wifi calling is not working. (***) and up to date have received no reply. The issue is that the phone says to turn off flight mode, which defeats the purpose of the feature and this is part of your flagship phones. Samsung technician Nicolas Jacobs has tested this feature on 2 separate devices of the same model (S22+) with the same outcome. He also tested this feature on a Z Flip 3, Note 20 Ultra, A53 & A13 and it worked perfectly. The software on my phone is updated but the issue still persists. I need this feature to function as I work overseas frequently and also have a late stage dementia patient at home,incase I need to call an ambulance,during power loadshedding. The device is still within warranty and Samsung should rectify this, as it could be a batch fault, or are selling a product, that does not conform to specifications as an entry level phone is able to perform this function.
