False advertising

False advertising. Upgraded cellphone contract with the "Free Samsung Ear Buds". This was done before end of August. It was delivered via vouchers on the 1st Sept, no ear buds. When I contacted my Service Provider, they advised me to contact Samsung. Samsung is now saying it was limited to 4000 customers and the banner was removed, however it was still showing on the Service Provider's website, hence the main reason I opted for that specific phone. Samsung do not want to even try and assist, just saying I must sort it with my SP. This is very poor customer service and false advertising on both parties sides. If I could cancel my contract I would and never support them again.
