Poor service from Samsung

I have a Samsung S10 that is under a year old and still has a warranty and I have been getting an error on my phone so I cannot charge my phone. I took time of work and booked it in at Vodaworld repair centre. When I collected the phone it was working, and then the next day it gave the same error. So I called Samsung directly and advised they should make arrangements to pick the phone from me because I cannot take more time off work. And I need them to either repair the phone properly or replace the unit. Its been a week and It hasn't been picked up and I depend on my phone for work duties. When I called to follow up they advised the courier van broke down. I find this hard to believe because such a big company cannot make alternative arrangements with another courier company. Very bad and unprofessional service. I am still waiting to be assisted.
