I bought a Samsung J1 in May 2015. Since then it has had several problems. Communications cut, and internet applications are too slow. I took it to the after sales service three times. The same defects persist. When I took it for the forth time, they still wanted to repair it. I demanded a new phone. Now I have been without phone for two weeks. Each time I call the help line, or I contact the after sales service in my neighborhood, they say they don't know when I can have a new phone. That is not an adequate situation. I have been loyal to Samsung for more than 16 years. Now I doubt if I may buy another Samsung product. For the moment I need a new phone urgently. Can you please urge them to provide me with the new phone? Thanks.
