Terrible customer service

I sent my Samsung Note 10 for a warranty assessment 08/07/2020 and I have received no feedback with regards to my phones whereabouts. I've made countless calls to the service center as well as visiting the store. This phone is used for business and due to their lack of customer service satisfaction s****s I'm left without a phone that I am currently still paying for. This matter has gone on long enough.
