I'm surprised how could an e-commerce website of that size don't do the basic operation policy of things or returned items for examples!
I've bought a S pen in Nov 19, returned it the next day and the same was reflecting in my account. accidentally today I found that they have not returned the money to my credit card. chat with customer service and what I heard was 'sorry for inconvenience, we will place a complaint' how could a website of such business nature does such mistakes?!
