Bad pathetic service and inconsistency

Jet Stores is tarnishing TFG's name , I'm a foschini customer fr decades and have never had any problems I do laybe's all the time and have never encountered any difficulty but Jet stores. I specifically have a problem with Jet store Protea Glen Mall last month I wanted to make a laybye for items worth R300 and was told their minimum amount for laybe is R500 and I left the items, two weeks back I was at Westgate mall I wanted to laybe 2 items and was told the minimum amount is R500 I left the items but when I requested to make a laybye at Maponya Mall for items less than R500 they did it with pleasure I received an exceptional service without attitude trust me, yesterday I was at Jet Bars yoh that store is worse is like tarven I took two tracksuits to the till and got through to this very rude lady who was wearing a crop top showing off her belly and she told their laybe minimum amount is R500 with attitude and I asked her to set the items aside for me and she said she would set the items aside if I ask her yoh I was so disappointed and left them there. Those cashier's needs to be trained . My question is if Jet is TFG why is there a specific minimum amount on the 3stores namely Protea Glen Mall, Westgate and Bars mall I think this an abuse customers but thanks to Jet Maponya for complying with TFG policies. You know at Foschini I laybe with as little as R200 without hustles
