Never again

I bought a wrong perfume online midnight then in the morning I called and asked to cancel, which i was then told they dont do that, so i must wait for delivery then take it to ANY element store. I recieved the product went to element greenstone to my surprise I was told they wont take the perfume coz they don't have it in stock? I call online customer service and I am told it's at the managers discretion to take it. I have never in my entire online shopping experienced such nonsense, what must I do truworths run around the whole joburg to return ur item? M going to return everything I bought last week and cancel your store card, your costumer service is non existent.
