Disappointed in Samsung Promotion and Customer Care

In June 2020 I bought the new Samsung S20 Ultra. With this purchase they had a promotion on free buds. This was one of the main contributing factors to me been convinced to up grade from my Samsung S9. The guys in the store advices how to claim my buds and all was great. When I got home I registered on Samsung Members as they said and could not find the promotion button for the buds. So I emailed Samsung. I was advices to email *** which I did. Someone did respond and requested information which I sent. They confirmed I qualified for the promotion and that they would escalate the issue. Once a week I followed up with no reply. Adventurely I noted the Samsung buds tab on the members page and registered there. I received confirmation i qualified and they gave me the reference number to confirm my delivery. Time went by so I started following up with Samsung mobile phone customer care. The first person I spoke to said all was in order and I should contact the courier company. "That was another mission" with no luck. I contacted Samsung back again where the next consultant told me I did not qualify for the buds. This was after 3 months of following up. I was very upset and disappointed as I had been through all the processes, was told by them my buds were on the way, received email and sms confirmation of my order. At this point I was considering what to do about this. It doesn't help escalating this to there customer service as they were the ones stuffing me around. About three weeks ago I got a call on a Monday morning from a lady at Samsung. She apologized for all the inconvenience and confirmed my buds would be delivered on the Tuesday afternoon as this is when the courier company operates. She also said she would personally call me the Tuesday afternoon to confirm i received my buds. I was very excited after all the stress and time this simple thing caused me. However up till today I have not received any follow up phone call as promised, I have not received my buds as promised. I am very disappointed in Samsung and the unprofessional they have dealt with my issue. Its been 5 months now since I first got the phone and claimed the free buds and I still don't have them. May be its better to stop supporting them as we have been doing for over 15 years.
