MTN ripped me off took my money and never delivered it's been three weeks now

What should've taken three days for delivery hasn't been delivered for the past three weeks. Worse part is this company is calling me a customer even did send me a statement for a product I've never received. They've been running around in circles and no one can give me an answer as to why they ****. Just a question as far as my knowledge goes it's falsely advertising to advertise three days and you haven't delivered three weeks later according to The Consumer Protection Act. And since there's no resolution I'm planning on taking this further cause MTN took my money and didn't deliver any kind of service or product. I regret doing business with them cause clearly they only care about sales and no service at all.
