inferior product and terrible service

i am a owner of many samsung products tabs, cameras, TV and the galaxy S5<br> this phone was rated a very popular phone with awesome features<br> i wanted 1, but when i received the phone i had endless problems and issues<br> i have not been able to have any peace of mind because of this phone<br> i am a business owner, from the time i got the phone it has gone back to Samsung 4 times and they changed the main board twice already<br> the galaxy S5 is a real waste and i would like samsung to contact me in order to rectify this horrible experience. i am so afraid of ever owning another samsung as i have very little faith in the brand and their capabalities
