Irritated

On 23rd July I got the email that I was a winner of the samsung buds as I reviewed the Z flip on Samsung members. As requested, I gave Samsung my details hoping I would get the buds. 5 days later, I got another email, that the email that Samsung sent me was a mistake and I wasn't a winner, as the competition was only for the Z Flip members. I called Samsung call center, spoke to a lady, she told me that the competition was only for the Z flip customers. This was a lie, as when I entered the competition, Samsung never mentioned the competition was only for Z flip customers but rather for Samsung members. When I asked for a reference number of the call, I was told that the reference number is their customer number, I was told one of the supervisors would call me, but alas, up to now I haven't heard from them. For a big company like Samsung to make a mistake like this, its embarrassing and a shame. I would like Samsung to contact me and let me know what really happened here
