firstly incredibly difficult to converse with a genuine technical person not just using a script with polite but hard accent in English. despite my recording a noise on a specific washing machine program because engineer eventually after two days of hard telephone calls came and says nothing wrong. but he refused to run machine on program that makes most noise. now wont come out again. Samsung proudly say 76% customers happy with service. well i would be ashamed of such a low satisfaction look at the pages of web site complaining bitterly. I wont buy again despite being 9 samsung device owner. washing machine was top of range £1200. note I used chat, telephone and email communications. tried to leave media player recording here but site wont accept. toy would be shocked at the sound. one star is too many
