Team leader but with ZERO customer centricity s****s

I queried an item which I bought online as I apparently processed the wrong size. I called the call centre 5 times and only one of those 5 times a consultant responded. This consultant then said she would call me back soon but only to call 30 minutes later and by this time I had already started an online chat with another consultant as who makes a customer wait 30 minutes. The online chat consultant could not assist me with the branch that had the item in question in the size I want and I asked her to then pass the message on to someone who can assist me. Her team leader Carusha then said she had called me but I never answered but funny how I never received the missed call notification. I then went through the story with said team leader who was the most unhelpful customer service agent EVER, she just gave her facts and hoped I would leave on my merry way with a solution that did not SUIT ME, A PAYING CUSTOMER. If I was asking for the items for free by all means act a bit *****y but not when I still wanted to continue being a loyal customer. I then went on to send her another mail and no reply. A day later I sent Carusha a mail to get her manager to call me since this product was not in the western cape apparently but could be shipped to me in 2 days????? So where is this item then? BUT still no reply. So all I want right now is Carusha's manager to contact me and provide me with a solution that suits me!
