bad service i received twice in one store!

Yesterday I went to Ackerman's at Alberton city to exchange my daughter's clothes to a bigger size, when I arrived at the door i approached another guy working there was standing by the do, I wanted to find out if I can go with the items inside or should I leave them with him like other retail shops they take them to the tailers you get them at their till, before I even finished asking him, he looked at other direction and spoke to his colleague, I noticed that he's not gonna help me because they were talking as if I was not there or didn't ask anything, then went inside with the plastic I was carrying, when I arrived to the cashier who was assisting, she called for authorisation apperantly it was the same guy who gave me attitude his name is Thabo"supervisor ", he stopped to the last till talking to someone else who didn't call for authorisation and was not even with the customer, the lady who was assisting me called him for the second time, he continued to talking then later after 5 minutes he came and authorised, he didn't even apologies or greet me, then he left. And that was not the first I received bad experience I had but I kept quiet. Two weeks back I wanted shoes for my daughter, there was a big lady standing by the door, I greeted her and asked if they do have sale in their store since I was from Edgars I noticed that they had sale that day...she just said yes then I said where can I get clothes that are on sale for kids wearing 18-24 months, she said I should check everywhere, I immediately left the shop. Today I called their complaints department I told them the whole story, they put me on hold them later they said they will call to give me references number after 5 minutes, am still waiting since I called at 08:48
