Order unfulfilled

I placed an online order in the 23th of September, a week later i received an incorrect order. I flagged it with the store and was assured that a replacement and collection will be made as soon as possible. On the 7th of October, i got a call confirming that my order will arrive on the 9th of October. The order was never delivered. On the 13th, the courier’s collect the incorrect order delivered and my parcel was still not delivered. I called the store again on the 17th and was assured that the order will be delivered on the 20th, again nothing. Please refund my order and delivery fee as the order was not fulfilled. I am really disappointed with the centurion store and overall service.
