I happened to purchase Lady Bridgerton's Masquerate Ball kits separately last night, then I realized I could purchase in bundle which is cheaper and get 3 exclusive items. Is it possible to get a refund in this case? 

I tried to reach out to live advisor yesterday, there was a case created saying they would reply to me through email. Is this how it works? I have not receive any email yet.
