Pathetic Service From Store!! NEVER GO THERE!!! waste of time!!!

so I buy a phone from someone who is immigrating... they give me proof of purchase etc... they reset the phone in front of me... i take the phone home charge it etc... factory reset my current phone to give to my daughter... switch on the phone google message appears "phone was reset" please use account last associated with phone, i google for answers find out that its a security feature for android phones... Samsung says go to a reseller and they have the tools to unlock... phone goes in on the 19th.. they get questioned on the 20th they say it should be done 21st ( not interested and no-one knows whats happening ) 21st we tell them we need the phone because we going to jhb 12pm on the 22nd still no luck phone a buddy from Samsung he says it shouldn't take more then 1 hour to resolve?? so are they just lazy...? honestly... now im sitting in JHB without a decent phone all because they did not do what they had to do... how can Samsung say it takes 1 hour, however Vodacare mimosa mall says they sent numerous emails
