Bad Attitude and lack of knowledge

i have recently booked in my Samsung device at the care centre within Dion Wired. there seems to have been a terrible language barrier between myself and the consultant which i was being assisted by, i had to ask about terms and conditions which were supposed to have been explained before i sign any document, not assuming i am going to give my phone away and deal with costs if that were to arise. to make matters worse, while i am asking this guy all the questions to cover my own back, the other consultant interjects with an irritable attitude and basically makes it seem as though i am at fault, wouldn't she want to know where she stands if she were in my position and all she was told is that she needs to sign. there was no mention of how long the repair would take, unless i had not asked. the service delivery is rather pathetic
