Extremely angry customer

I would like to report a ********** company called Nuviantecare, the website is called Nuviantecare.com They are apparently selling eyelash serum called Nuviante, which they advertised as being on sale. After adding all my banking details and home address the page kicked me out, so I went into my bank account to check if the money had been deducted and it was. So I emailed their address to check if anything had been processed and they confirmed that the the order had been recieved successfully and that I would recieve my package in 14-21 days. After 21 days had passed I emailed them again to check on the progress of my delivery to which they responded that it would take 14-21 "business days" and then said that due to high demands at my city's post office they have been experiencing delays and it would take 3-6 weeks and apologized for any inconvenience, and also provided me with a link to their couriers with a tracking number but when I went onto the link using my tracking number the last movement took place on 19.08.20 which showed that it departed from Asendia. So I waited up until Monday 28.09.20 which was a total of 7 weeks and then emailed them informing them that to date I have still not recieved my package nor any communication regarding the delivery of my package to which they responded that I should check with my post office and that they do not recieve any tracking number once the post office receives it and that I should let them know that the package was shipped through Asendia. I have still not recieved anything and inlet them know that I think that their company is **********. I just want to warn future customers of being ****** by them.
