i played on my main apex account since id say mid season 8. come to the season mad maggie came out (i forgot what season it was) i started playing on my microsoft account (i played it before like one or 2 games before season 1) bought 2 heirlooms and overall spent lots of money and time on that account and was on and off playing on my main account. now come october 2023. ea had been slowly letting out cross progression. now december 2023 when everyone can do it. i contacted ea support to figure out why nothing has happened. goes as follows. me "i would like to know why my stuff hasnt been merged/transfered since cross progresion came out" ea support "sorry but this is 2 different accounts. would you like to unlink microsoft account from this account (alt) and link to current ea account to transfer everything" me "yes  please". then we go through everything and everythinkg is all et good to go. then now i would like to play on my alt for a bit and use some cosmetics that i have on that account. so i contact ea support. the person i was taliking with was very very helpful. then he told me that it wasnt possible unless someone higher up were to do something. what happened was that since all progress on alt account was dont on xbox that stuff was deleted apon linking. now i wasnt told that would happen back in december of 2023 when i did unlink it. so know 1,500ish CAD (about 2,200 USD) was now gone. if anyone anywhere could help me get a reselution to this it would mean alot to me as it sucks loosing over a grand of items wihtout warning or anything. than you in advance. if anyone else had something like this happen pleas
