MOST RUDEST PERSON

My fpartner went to Edgars in Northgate today as I asked her to please go buy me a shirt and I gave her my edgars card which she has been using since the day I opened my account. She went to the customer service tills to pay and there is that Indian lady working there, I think she is the manager or supervisor in that section but she is the most rudest person out there, I cant even understand how she can still be working there as this was not the first time we have had problems with her attitude, the first time was a while ago when I wanted to open an account and I was declined at that stage and she shouted out and laughed while saying to me IT IS DECLINED BECAUSE YOU ARE BAD LISTED in front of a whole que of people standing there , now with my partner today she also shouted at her saying she is doing ***** because it is not her card, this woman even phoned me and I confirmed that I know that she is using it on my behalf as she has been doing for ages on but this woman was so rude and shouting at my partner for doing that and saying she is busy with ***** even after she gave them her own and my ID books as proof and that as well in front of a long que of people standing there CRAZY
