Bad Service and No reply from ''CEO''

I am really disgusted with the service I have received from Samsung!To cut a long story Short- My fianc? purchased a Samsung Galaxy Grand for me while working in Iraq,after a week or so the phone started developing pop ups and virus and downloading apps by itself, when the Virus completely took over my phone I headed to the nearest Samsung store 130km away from me,I then found 3 different stores which each gave me a different verdict on the phone with which I was not impressed! Finally at the Samsung SmartCare centre in Constancia Kloof they advised me that my software was ******* and needed to be replaced! After waiting for 2 working days for a 'repair' I had to pay for + all the petrol money I received no response so decided to Call them myself-NO ANSWER ON ANY OF THEIR LINES,I then called the samsung call centre and they informed me the job was completed I drove another 130km(ONE WAY) to collect the phone where I was informed it was not repaired as the Motherboard was dead! After such a waste of time my brother in law had a look at the phone and ran it though a anti virus software! The Phone is on and working yet Im still getting viruses! Samsung Please do ur jobs and contact me
