South Africa Samsung giving Samsung a very bad name

Good day, I am having the worst customer service from Sasung South africa you can ever think of ! I gave my phone in for repairs in Aug 2017 and they lost it. After finding it 2 months later I asked them to deliver the phone to me and it has now been a month and still not delivered. They keep telling me stories and I feel like crying at this stage as i really just want my phone back but the ignore or tell me lies every time i phone. They are also very rude !

Could Samsung UK help me, I dont know what to do anymore.
