2 months to fix my Galaxy Note 3 and still running

Sent my galaxy note 3 in for repairs at Samsung Eastgate on 27 December 2014.Got it back unusable on the 7th of Feb 2015 so took phone straight back to repair agent Powercare on the 9th of Feb 2015 to remove network block on phone after initial repair.First response from samsung was that they needed my proof of purchase again and photo of error on phone \enter network unlock pin"when phone starts up.That was on the 16th of Feb after phone was back at repair agent for a week already...Now on 2 weeks the repair agent is still waiting for code.I've also logged complaint at samsung but not getting anywhere fast...Promise to phone me back but they dont and unavailable when i phone them again.Tomorrow it will be 8 weeks since I originally sent my phone in for repair on ADH premium and my phone is still unusable lying at powercare Edenvale while waiting for a code from samsung to unlock"""
