Appalling and Pathetic Customer Service

On 28th June I went to sportscene canal walk for the sale they had. I purchased a pair of Dual Tone Nike sneakers at literally half the price and I was very happy about it, however when I eventually wanted to wear the sneakers I found that it was "2 left shoes". When I got a chance on 8 July I drove all the way back to Canal walk where I told the sales rep I am not impressed as this was supposed to be checked by the cashier before I left the store but she did not. I gave the slip and asked them to fix it. I was advised that they do not have my size in the sneaker but upon checking the system they found that Parow and Promenade has my size. I told the rep that I refuse to drive around as the cashier should have checked before I left the store on the day of my purchase. She then called Dayne (not sure if he was the store manager) who assured me that they will rectify the issue. When I asked how, he rep**** " we will order your sneaker from one of the stores that has stock and one of our works lives in your area so he will deliver it to you and you can give the other takkies back". I asked Dayne by when will this happen, his response was on Tuesday we will deliver it. I told him specifically that I will hold him accountable if he does not deliver as this is a huge inconvenience to me as a customer. He confirmed my address as well as contact number so that he can keep me updated. Tuesday passed I never received any call from anyone at sportscene and no one was at my house. I decided to contact the store and Dayne advised that the guy was at my place twice but there was "no one". There is always someone at my house all day and I was at home from 15:00 but no one pitched. When Dayne confirmed my house number on the address he had it wrong even though this information was confirmed on Sunday. He then told me he will contact the guy to see if he can still do the deliver the shoes and call me back, 35min passed and still no call back from Dayne and the canal walk store literally closes in 10min but no call back. I called the store again for an update and he says "I was about to call you", the guys phone is off and I cannot get hold of him. I asked him to escalate my case higher as the service is appalling, there is no urgency and why do I have to follow up for a mistake made by the store. He assured me I can escalate the matter to his manager or the area manager but I am still waiting for the contact details that I was supposed to receive on Tuesday 10 July 2018. I am very disappointed and disgusted by the pathetic and appalling service that I am receiving from Canal Walk sportscene who happens to be one of the biggest stores in cape town.
