Ordered and paid but did not receive product over weeks

Very disappointed and dissatisfied with their service. I have ordered a product for R400 2 weeks ago and still have not received my order. Before placing the order I was told I will receive my order between 1 - 4 days but after I have paid them. I have been getting excuses but did not receive my order. I have all the proof. I feel ****med and now I just want my money back because they don’t deliver what I paid for.
