ONLINE SHOPPING - INCORRECT ITEM DELIVRED TWICE

I had placed an order for athletic leggings two weeks ago on order P***, as stipulated and advertised on their online shopping site that this legging is black with a white and red logo, upon collecting the item I realise that they had sent me leggings with white and grey logo which I already had. I then returned this the store thinking that it had been sent to me in error. I then placed another order that day, P***, for the red/white logo legging and after placing an order I immediately called and sent an email (CS-345814) to make sure that the online team does not send me the incorrect item once again, and I was assured by the lady that she will pass on the request to the online team and according to the mail I received, the issue was resolved. I collected my order today only to open the packing and find out that they had sent me the incorrect item again. I do not understand this, your items online are either advertised falsely or there is an error with the SKU numbers, whatever it may be, it’s not my problem. I ordered a specific item and expected that item delivered to me. I need the online team to fix this.
