Very Poor Attitude

Good Day, <br> <br> i bought a JAWBONE from the Cresta dis-chem in MAY 2015. I used my Discovery benefit to subsidize a portion of the cost. The device became faulty and returned it on 19th August 2015, and started dealing with Helain. She said that because the device was claim through discovery there had to be a reversal process which takes 48 hours to be processed and i was told by Helain that everything would be sorted by Friday 21st August. The replacement Jawbone device was also faulty, but now cresta has no more in stock, and when i phoned on Thursday 20th August to let Helain, i was told she was off and had still not processed the reversal(As she had promised to do). Yesterday i went to the Bryanston Dis-Chem(Under the impression that the reversal had gone through) to try and get a new device, having the replacement Jawbone(Number 3) in hand, i was told that no reversal had been processed. I walked out empty handed, and phoned Helain to find out about the reversal, and she told me that it is not her responsibility anymore, and i need to check with the person who deals with it, and then put the phone down on me. The whole experience with Helain has been very unpleasant. Very Rude!!!
