S6 Edge sim card, sim tray both stuck

So I had to change my S6 edge’s battery recently and it was all good. After some weeks I tried to remove the sim and noticed it’s not coming out. Then I gave it to a repair shop in my local area and they said they can’t remove the sim because it seems like previous battery repair guy has mistakenly glued sim and tray into the motherboard. When I asked them to remove sim anyhow they said that will damage the motherboard so they won’t take that risk by any means. My main doubt is, if they use uv loca glue to attach back panel after battery replacement, why they cannot reverse it by heating. I know this sub has many experts as I followed this for some time. Anyone got any resolution for this? Thanks in advance.
