i personally has experience of 8~9 years with Media In, ISB.
i do not have any complain regarding their service, yes, they are not a manufacturer or even importer of any PC item, therefore they are bound to policies and warranty conditions of Galaxy, Shingtech. etc......, and we all know that Shingtech has worst warranty backup in Pakistan, then comes MSI importers,
therefore, sometimes a customer might not satisfied with MI due to background behavior of Shingtech or others
otherwise Media International then PC House are best shops in Islamabad regarding customer satisfaction, i am dealing with both since 2001
