When will Xfinity mobile hae the technology/capability to correct outgoing caller I.D

I have been  with Xfinity for over a year. When numbers were ported from T-Mobile, 2 lines had correct caller ID, mine and my wife's Id was transposed. When I checked, was told that it would have to be corrected at an upper tier level. Both numbers then became "Wireless Caller, I have contacted support, I have even contacted Verizon and was told that it is Comcast problem. When contacting Comcast again, I was told that they were hoping to have the technology this year. In talks with support, It is been suggested that if I want my original Caller ID, maybe I should change carriers. Also suggest to get TrueCaller app but to work, anyone receiving calls would also need TrueCaller.  Extremely frustrated.
