Received no feedback of Vodacom Cape Quater Cape Town for more than two weeks

On Monday 14 August 2017 I have giving my IPAD in to be reset to Factory Settings, the saleslady called the technicians and he took the IPAD in to be reset, on Wednesday afternoon I received no feedback from him and went back to the store. He was out and this was about 15hoo in the afternoon, the saleslady could not help and I had to wait for him. He casually walked in after 15 mins and said he was about to call me as he could not charged the device and are trying an other charger. When I called on the 1 September 2017 at 17h46, Cikizwa confirmed that she does not know anything off the device, the technician left for home and there is no Owner/ Manager or Supervisor available as they all left for home . . . I am a bit concerned about this as no one can give me any answers.
