I used a discount voucher with limit of 1k and I was able to maximize it because I purchase mobile worth 40k. However, shopee cancelled my orders and froze my account. According to them, I used a shipping voucher multiple times which doesn't make sense because once voucher is used, you won't be able to select it again. I lost the discount because of that and they can't even give me proper explanation. Even asking me to give letter acknowledging the violation in order to reinstate my account.
