Nightmare getting help after wrong product delivered

I bought a plush blanket from Mr Price online and within 5 days I had the blanket. 10 minutes after the courier left I opened the package to find the incorrect blanket. I sent a message on the "chat" line but no response. Unfortunately there is no records kept of the chats. I asked an agent this afternoon how do I go about having the blanket collected and the correct 1 delivered and was told to go to the shop which sent it to me?.??? Was it not online from a warehouse. Apparently it will take 4-6 weeks to to collect and no mention of when the correct 1 will be delivered. The nearest Mr Price is 60km 1 way from my home. Who do I contact to correct this considering I have paid for the blanket as well as the delivery. Maybe Mr Price should ask Takealot for some assistance in online ordering. Can someone contact me A.
