i accidentally purchased 2 quantities of 1-day Korea eSIM Red and i only need one (yes, i am that stupid. *note: the site already gave me heads up that i was purchasing the same product 2 times and asked me if i still want to continue but i absentmindedly tapped "yes" because i was panicking*) i immediately messaged the customer service for a possible refund and still got no reply but because the sim that i bought from the airport is about to expire, i decided to read once again the precautions of this site and saw that refunds are impossible (unless they considered your case carefully just like that one review here) but then thankfully, the  qr codes that were sent to me (they sent it in a flash btw, everything was so fast) were two different qr codes (as it should be because i bought 2 quantities after all)  so  ! i just decided to keep the other one for my next trip here in south korea because it can still be activated 1 year after you receive the qr code. to add, the eSIM is working well! its my first time using an eSIM and my cellular network went from KT to SKT. the signal is good and is just as fast as the other physical sim that i bought from the airport. 

i will surely purchase from this site again because aside from the fast transaction, its very affordable too! thank you so much krsim!!
