Nykaa.com — Gift voucher missing.

I purchased a gift card for a friend for her birthday and i made the payment online and received a message just after that which says that the gift card has be sent to my friend on 4th june 2022. i recently asked her for the card and she said that she has not received and message or anything.
after calling nykaa customer care, they are saying that have sent it and check it again or your phone has issue thats why yopu are not getting the message and being very rude that hy you waited for so long to raise the complaine and this is not our problem now and your friend must have used it and things like that. is this the way to talk
