S10 Buds Bad courier company.

I pre ordered and purchased the samsung Galaxy s10 as i was aware that i would receive a free set of galaxy buds aswel as a 500 voucher for samsung accessory (this was not the case as the voucher could only be user online and for a cover only) besides that is not the point the point is that i have now been waiting sinve the 11th of march for my delivery on my Galaxy buds and they have everyday been stating that it will come but it hasnt come i understand this is not Samsung at fault but i have emailed samsung with no response at all. i insist on getting my galaxy buds delivered using another courier company not Courier it as they are useless and they are actually impacting samsungs customers due to there poor service. this is really rediculous and i would either like my item being delivered immidiatley using another courier company or i shall demand a refund and would rather go to court and spend 10x the amount of an S10 just so that i can get my valid pount across.
