Poor Edcon service and unhelpful staff

My mother handed her tablet in at CNA Somerset Mall as it needed repairs, this is the second time it has needed repairs so it was obviously a poor product to being with, but that is not the main complaint. Since handing it in the last time CNA has closed there, so she was referred to Jet to collect it. She has gone there numerous times and nobody seems to know anything about the tablet and cannot locate it. She has been given two phone numbers to call but on both ends they are totally clueless as to what is going on. It was handed in 20 July 2018, so more than a month and a half and nothing.

We would appreciate prompt feedback regarding this matter and if this tablet can truly not be found then a suitable replacement be given.
