I Store the Glen: arrogant staff with no customer service

On Thurs 28/11/2024, I went to the I store at the Glen with the intention to buy 2 Ipads 10- 64g , 1black & blue. I store black friday special ran from the 18/11/2024 to the 2/12/2024. I was assisted by 3 sales staff, the senior being Theresa. There was no stock of the blue so I bought only the black. I asked multiple times and was assured that the blue was in transit , they coundn't tell me when it would come but would contact me when it did and I would receive the same deal . My pensioner mum was with me and asked if they would throw anything in as I was buying 2 Ipads . She related that she had bought a lap top at the Rosebank store and they threw in a bag . Theresa asked my Mum, if she hadn't gone to the second hand I store. My mum became visibly confused because she hadnt know there was a second hand store. I didn't complain about the slight because it's convenient to get my stuff at the Glen. On Saturday I called the *** and waited 20 minutes each time. No one answered . On Sunday , 1/12/2024 , I went in and was assisted by Minka, who said that they couldn't assist me as their Ipads were sold by Friday morning, that no Ipads were available countrywide and when stock came in , I would not receive the same deal. When I pointed out that an I store a senior sales staff had assured me that I would , Minka told me that she could not assist until Monday , when she would talk to Theresa and find out what happened, the insinuation being that I am not telling the truth. When I pointed out that the transit stock must have arrived for it to have sold it on Friday ,and no one bothered to call , she had no answer. Minka also refused to give the head office number for me to lodge a complaint. Istore SA, your sales staff represents you and if they commit you should honour it. This experience is a poor reflection on what training your staff receive as they obviously think customers are idiots who are led by the nose.
