downloadinstant.com , minutedownload,com They took my money without providing the promised product Internet

I paid with a credit card for a download of Microsoft Office Home  and Student 2016. I received the download but did not receive a legitimate key to actvate the program. The program is only good for 5 days without activation. The werbsite promised a lifetime license activation. The support phone number is not a working number and there is no response to the online support. They have stolen my money. I made multiple attampts to call the minutedownload number and got the same response each time. The phone is answered by automation claiming they are experiencing too many calls and I was to try the www,minutedownload.com site. It is bogus also.
