Poor Service

I ordered tiles and laminated floors online on Friday (24/11/2017) with the option that I will collect it at Brits. The site accepted the order and the payment with no problems. Today (27/11/2017) a gentleman phones me, with the name of Thabelo Pitso and tells me that they don't have stock. This was not shown on the website as the order and payment was received without any problem. Furthermore he informed me that I can either pay extra for delivery from the Mall of Africa or wait until March 2018 when they get stock again. This is totally unacceptable. Now I have to pay extra for delivery from another branch or spend extra fees on travelling to go and collect it there while there was no problem in receiving the money and the online site also advertised this as a product that can be purchased from this store. (Not indicating that there was no stock) Hopefully this is not the kind of customer service that CTM provides to consumers and can make a plan ?
