Seems customer's right and satisfaction means nothing to Samsung. My Samsung S4 mini had battery issue out of the box. Their warranty repair is a joke! !!! They keep sending me the faulty phone back! Has been sent to them twice in a month and it's still faulty! I did report it and was told to send it back again.!!!!! ... it's clear their "engineers" aren't qualify and they don't really care about it. Their escalation complaint procedure is to send a postal letter to the address in Sheffield. ... And the results would be NOTHING! they would send you a letter saying : Ah. .. send it back again! !!! This is obviously the reason for such a BAD service ..the customer service team knowing no one is actually care about the customer, service and their failure.... They know customers are out of options ....
