Unable to access other eSIMS on new iphone16 purchased through Xfinity

I was told by the sales agent in the Xfinity store that I could access the other eSIM ports while traveling abroad. My husband and I both travel for work and need to have roaming data using local eSIMS (the global pass it too expensive for us). We also travel abroad for several weeks as a family). We specifically asked if this was possible when we opened our contracts and took advantage of the phone credit divided into 24 months. 4 months later my husband is on a work trip abroad and can not access the other eSIM port because his phone is locked. I spend about 2 hours trying to get a representative on chat only for them to tell me i need to go to a store. I finally go to a store and they tell me that they can not unlock the phone unless i pay it off.  We just entered into the contracts so it would be a big expense to pay off the 4 phones all at once. I decided to think it over for the night. The next day I chatted with a representative ready to initiate the payment thinking I could just pay off the phones and would still receive the monthly credit as long as i kept my phone contract. The representative said they could unlock the phones without me needing to pay them off. They proceeded to unlock them (at least that is what they told me) and wished me a good day. I informed my husband so he could try to use the local eSim card he had purchased only to find out the phones were never unlocked. I got back online with another representative onl;y to have them tell me the phones can not be unlocked (the previous person had lied to me) unless I pay off the remaining balance (again only 4 months into the 24 month contract for 4 phones so that is a lot of money at one time). I asked if I did pay off the phones if they would unlock the devices...They replied 'Yes, BUT I would lose all future credits for the phones'.   I was really excited to switch to Xfinity when we made the move, we got a good deal and were thinking Xfinity would be a long term place to combine out cell and home internet services. Now I can not wait to switch. The deception and lies it too much for me. I have spent easily 4 hours on this issue over the past 4 days. Why does Xfinity lock the eSIMS for loyal customers, especially in today's setting of global travel for work, vacation, and study abroad? Why are Xfinity employees so misinformed or are they lying for a good review and to get a sale? I am hoping Xfinity can help me find a solution to this conundrum based on deceiving practice (lying about being able to use other eSIM ports) to ensnare customers into new contracts. We NEVER would have agreed to a contract that restricted the use of eSIM ports for 24 months being an international family living in the US.
