Worst supervisory experience 1007

I am appalled by customer service from pick n pay ASAP ,I placed an order on 2nd September 2021.i received the incorrect order and logged a dispute with the call center spoke to a ms Smith who logged the dispute and said she will call the store than get back to me in 30mins she did not of course ... I called back than spoke to supervisor Sibusiso Liga who assured me that he will assisted with my refund of my funds and R100 promo code for the inconvenience.He promised me an email in refgardt o discussion and way forward I waited 2days , I called back and made him send me the correspondence on email which he eventually did .i waited a total of 2 weeks for refund that was suppose me to take 2-5 days . I called today to follow up and the game tells me that she can only see request for promo code but no refund should she will investigate! I than was transferred to Sibusiso in which I asked for his seniority as clearly he saw no urgency in my dispute ,he than transferred me to Janine who I late found out was his consultant and not even above him .she came onto the line to say the lady who is dealing with my refund will call me to advise he delay I asked her how will that help ,she than transferred me to blue hills store .I called back spoke to shakier,he than tells the refund was not processed correctly and he will deal with it internally wow now I’m told that I still ha e to wait the standard waiting time for he refund which is 7 days wow pick n pay wow.mind you they have never called ever ever !!!
