Galaxy s24 plus purchase from Comcast will not stay connected to their phone network

For several months my Galaxy s24 Plus will not stay connected to Comcast phone network making me reset my network in order to make phone calls. Have contacted them probably 40 to 50 times and now reset my network myself as they have no help And do not escalate the issue. The issue is not confined to my home it happens out of state and county. My phone number frequently disappears completely from their network system currently they have me hicked up to E-Sim 2 Network. Is there any way to ever fix this issue or talk to someone above a level 1 phone operator?
