Samsung Service ???? NO SERVICE

I bought a Samsung S21 Ultra 5G on the 12th of March. I registered to receive my free earbuds. I was told I would receive an email or sms with a reference number for delivery. I phoned on the 18th of March to follow up, and I was told my claim was rejected. I had to resend proof of purchase etc, which I did, and I then received an email comfirming my claim was approved, they will contact me with delivery details, it will be delivered in 7 business days. I responded to the email, and haven't had ANY response from Samsung. I have phoned 7 times, spoke to your customer service consultants, and EVERY TIME I am told it is escalated, the problem will be solved. I still had no response, I am disgusted in the poor service, especially after deciding to move from Apple to Samsung. Seems that was a big mistake.
