Angry customer

Good day So disappointed with a service received at southgate mall Woolworths branch after being a woolworths customer for so many years. I was there to return shoes as it was 1 size bigger I was assisted by the security at the door very welcoming and did what she is suppose to do and i took the right size that i wanted went to que to get assisted like every customer, I qued until it was my turn when I got there a lady that I forgot to take her name told me to go upstairs as she does not do returns mind you I'm with a 3month old baby I have to go the escalaters that are not working with the baby ok that's fine tried my way to the top and had to que again and got to the till was assisted by a lady by the name of vuyolethu if I'm not mistaken and by the manager named Del if I'm not mistaken and I asked why was I moved from downstairs to upstairs after queing so long the ladies showed no remorse and looked at me like I'm crazy I've never received such treatment from Woolworths it was my 1st time and they told me that I should know that exchanging goods are done upstairs how will I know that I do not work at Woolworths I am just a customer. What they've done to me is totally un acceptable . Stop undermining people by the way they look. So disappointed. Train your staff to do the right thing to other it's so unfortunate that the damage has been done to me I will never forget this day.
