Think Twice Before Buying Samsung Phone

                        I wrote following email to CEO of Samsung through their website

Dear Sir,

I purchased new phone Samsung J7 in KSA and found that it will work KSA'a SIM network only. You can't imagine that how I became disturb. In natural, most people know that a mobile will work in whole world, so I. After that, I called your customer care in KSA and told to go service center.  I went there but its was closed at time said by C.C. Now, I returned India but facing problems. Please solve my problems and in future, make all phones restriction free.
