Poor service online order not received long outstanding

I have ordered an item online on the 28.3.2021 on the click and collect option witch states 4- 7 working days for delivery, I have phoned Customer care line on the 8.4.2021 to find out if the parcel was at the store for collection, I was told that the parcel was not at the store and they will escalate it to the courier which is City logistics, I phoned again on 9.4.2021 which is already 8 working days(excluding the public holidays and the weekend) I was told that the item is still in Durban that is after 7 working days and I will only get it on the 12 or 13 April 2021 . This is not the agreement when the order was done. It also state that my parcel will be ready for collection on the 8.4.2021.When I spoke to the agent I was told that there is nothing they can do as to escalate it again to the courier. I am not happy with the service this will be the last time I will buy any product from MRP at store level or online.
