Poor Service and No Customer Care

I ordered a pair of shoes on Monday 04/12/2017 and received the item on the 06/12/2017, only to find that they brought me the wrong size. I received a box stating that it’s a 6 and a size 7 in the box, how does one check the items before they leave the warehouse. I then called the service centre and spoke to Hughlynne, Simvuele, Jade, Holly and a manager Moira Suntele informing them of this and was then told that I have to wait for the return policy of 5 to 8 working days, this is not me returning the item, the wrong item was sent to me, how is this my problem? I need this return done today and no later and to bring me the correct size as per my order today. This is really pathetic , it was the first time I purchased something from SUPERBALIST. I will definitely not be purchasing anything from them again. SUPERBALIST not so SUPERB after all hey!
