Bad service/ empty promises/ lack of communication

I have been buying from takealot all along i never had an a bad experience like this before.i bought facial products they delivered wrong things i had to wait another 2 days before they came to collect and now they suppose to deliver on 6th of may even now i have not recieved my order today its the 8th of may.i have been calling them everyday asking for my refund if they can't deliver still no refund .when you call them the customer consultant will say we will call you back. Takealot .com please refund me since u can't deliver all i want is my money so that i can go and buy somewhere else when they can give me what I want.im disappointed im never buying from you again
