Misled advertising...Samsung buds

I upgraded in May. I chose Samsung instead of Huawei phone because of the promotion. The promotion was if u take any Samsung s10 and you get earbuds for free and it was surpose to b delivered to me. Then started querying y its taking so long. They said only 2weeks.Its August and Im stil waiting for for the earbuds which i was surpose to get with the phone. I phoned Loyed Manuk several times and he said i must phone the call center number which does not work at all. Im getting no assistance n im driving my petrol out to vodacom n using my airtime but im getting no where.How do do you get no service for such a big company like Samsung? Im not being being compensated at all for the misled their putting me through..Really disappointed
