Western Union — issues of swift copy

Hello, i had made a transaction through western union on the 27th august’ 20 of £1530 to birmingham city university to their netwest bank account for certificate of application for study (Cas). Since university is demanding a swift copy or tt copy for the issue of cas i have been requesting western union for the swift copy or a tt copy through mails and speaking to customer care executives till date but there has not been any support or help from the western union. My course is due from 7th sept’20 and on the basis of cas can i apply for visa which will take 3 weeks and 2 weeks of quarantine once i reach uk. Western union is not ready to understand the seriousness of the situation.
