Please close your Online store and customer care department

I don't want to give them not even one star. Samsung you should close your online store and customer care department. It doesn't work. I have bought a Samsung Note 20 and according to the promotion they say that you will get a UV sterilizer for free. I send Samsung the details they verified it and send me that code and the code doesn't work. I am calling Samsung for the last 12 days for this matter. when I try to call the online store customer care they transfer me to home appliances and I have to explain to them the whole story then they say I have escalated to your matter it will be resolved soon when I ask them to define soon they have no answer. I have been transferred between departments for the last 12 days and every time I need to explain the whole story. Finally, when I had a chance to talk to someone from the online store he said he will talk to his manager and get back to me. I dunno if he went to Korea to talk to his manager because I never heard from him again. One more example of how careless and unprofessional they are. My name is Ajith and they miss-spelled it ajita . from the first call itself, I told them you have spelled it wrong and they don't bother to change it they still call me with that wired name which I am not
