Rude call centre agent and unhelpful in-store service

On Saturday I brought a per of shoes at south gate store. On Monday morning I went to work to my surprise when I walked out of the car I started get a sharp pain pin on my left leg that was around 7:00am in the morning . I called rage customer service they told me they only open at 9:00am. At 9 when I called they told me I needed to speak to Wendy and she was out I must call back after 12pm. I called again at 12pm then spoke to Wendy who sounded very bored and told me I must to any rage store. 4:30 I got to south gate they they called they head office and I was told that Wendy was of the office and I must came back at 5:30 when I went back at 5:30 they said Wendy said they must not exchange my shoes . Took the shoes and went home I called Wendy today and asked her about they damage policy and in a rude and disrespectful voice she told me that she is not going to exchange the shoes and I don't care about the CPA. She is not working for the CPA. Am not going to take this down so easy cause I have brought shoes from rage sandton and I always got great service but for Wendy to speak to me like am her child or one of they employees . After what happened today I am going to take matter forward and I am going to get my refund. Even if it means I go to all social media sites to talk about they poor service and lack of respect for they customers.
