Disgusting Customer Service

I am very disgusted by the service I received from your store on Saturday. I went to Mr Price Home at Boksburg Retail Park to return cushions because one had a tear, I was assisted by a lady called Tina her service was disgusting and she has a bad attitude. When I got to her till I informed her I was here to return the cushions and put them on the counter in its original packaging from the store and she looked at me and ask me to take them out of the plastic and give them to her. I could already sense the attitude and I politely took the cushions out and gave them to her as per her request. she looked at the cushions and called her colleague then they continued to speak under their breath and I heard her colleague mumble “it has been washed” bare in mind that I have not even been asked for reason as to why I was returning the cushions. After they’re conversation she turned around and called the manager on the intercom and just stood in front of me with no explanation at all. After a couple of minutes I ask her why I wasn’t being assist she said she was waiting for the manger. To my surprise I asked waiting for the manger for what she rolled her eyes and said to let me know if I can continue with this return. I said to her but you haven’t spoken a word to me since I arrived here and now you calling the manager at least let me know what the delay is you can’t just leave me standing here. She rudely responds saying “ Why you making a noise and annoying me” during this altercation the manger arrives and she also projected the same attitude towards me which left me baffled because as a superior she’s supposed to reprimand her employee for a bad customer service and attitude but not in this case she didn’t care or even bother to hear my side of the story. I really feel they don't know how to address paying customers. They thought they are doing me a favour I could see. if you still have such employees including the manager at your stores, then sadly I’ll never go back there. I hope this gets resolved before you lose many more customers and the Manager and staff take responsibility for their actions. She needs to learn to respect other people and love the job or give it to people who need the job.
