Galaxy s9+ only charges while off

I mistakenly purchased it from Samsung. Only thing they offer is return shipping, not overnight return and send in for repairs. I will be without a phone for 14 days as a doctor/surgeon unacceptable. Otherwise find a Samsung store and deal with it there. Not many of them. Best buy will send it back for me, per Samsung. Phone only 1 month old. I would recommend never purchasing from Samsung unless you can be without for 14 days.:'(
