Bought a samsung tablet from pc world in December. Just over 3 weeks ago it stopped working so took it back to the store. The assistant ssid it would have to back to samsung and would be about 3 weeks which is fair enough. Rang last week and rhe person I spoke to said it was on it's way back from samsung. Rang today and apparently it is still with samsung((??)) nd there is no timeline for when we will get it back. What is a reasonable to expect to get it back?
