THIEVERY OF PROMOTIONAL GIFTS!

I called Samsung weeks ago to notify them that I need to change my home address to my work address for the delivery of my gift and they assured me that I will get my promotional gift, A battery pack for the Galaxy A70 and the courier will contact me for me to change my details. I work in a Call Centre FOR CRYING OUT LOUD and can't always answer my phone during working hours. Now out of the blue, I get an e-mail that I forfeited my gift for not answering my phone, like seriously!? Why didn't anyone send me an e-mail about the delivery first time around when you couldn't get hold of me??? Because what you're doing now is ***** and ********! I work in customer service myself and we do not DO THAT TO OUR CUSTOMERS! We try by all means to ensure that we get hold of a customer. I don't want to hear any stories, I WANT MY BATTERY PACK NOW!This is ****gery and ********! You cannot by any means keep my gift just because I missed 2 calls only and you're only notifying me on the 23rd, more than a week later! WHY THE HELL DIDN'T ANYONE SEND ME AN E-MAIL ON THE 11TH!!!! Then CLEARLY IT SHOWS YOU DIDN'T WANT TO DELIVER MY GIFT BUT KEEP IT FOR YOURSELVES! SAMSUNG I WANT MY BATTERY PACK NOW I DON'T WANT ANY STORIES!
