Vodacom broke my phone in June2014 & still has it

June 2014,I took my phone to Lakeside Mall Vodacom for software upgrades.When picking it up the next day,it was broken.I told them & it was rebooked. After a week,it hadn't been repaired.I asked for the manager,a supervisor [Jason] promised to sort it out.3 more weeks passed,still not repaired & Jason told me that they were waiting on the Vodacom Regional Manager to get to my case.I waited another month then contacted them & they told me they were \escalating"the matter & it would be sorted out soon.2 weeks later"
