Poor customer service.

Good day i purchased four Samsung A33 phones a year ago and whitin the first month i had problems with them.All the phones had the same problem it was the charging port.it would keep on giving the same notice moisture detected disconnect charger we where told it was a factory fault.There where other problems but the issue now is that one off the phones that was repaired before with the same problem is doing the same thing and samsung isays the warranty falls away because of a small dent at the bottom of the phone.i will not purchase another samsung product aqain. I took it to samsung repair center umhlanga.
