MinuteDownload.com Gave me two key#'s that would not activate. Will not give me my refund now. Internet

On Oct. 4th 2017 I purchased Home & Business Office 2013. After installing product activation would not work. Tried several times, then window comes up and says this product is not available, will give you product key replacement, that would not activate also. At this point I call  MinuteDownload and this is what I get "Sorry all representatives are curently busy, please press 0 to stay on the line. So I do and this is what I get. " Thre  best way to contact us is by MinuteDownload Chat or Support@MinuteDownload.com.", then I'm disconnected.  So I got to the wbsite for chat and it says " Sorry all chat lines are busy try back later", that was Oct.4th around 1:30pm, tried back around 3:00pm still the same thing. So on Oct. 5th tried the chat thing again with the same results

. I needed my Outlook and Documents right away so I called MIcroSoft (the real company), told them what is going on, gave them the  1st Key# and I'ts not avalid product. They tried to install it on my PC and could not get it to activate. So they gave me free trial Office 365 and told me to get intouch with them to get refund. So today Oct. 11th. Finialy got on the chat thing after waiting for an hour, told Mark what the problem was, he wanted to see if he could install form his end, he need to uninstall Office 365,  said no, but he had to to installI said OK. He was using TeamViewer and we started around 12:38pm, he uninstalled Office 365 and installed somethig (Office2013)? . After it was installed he never came back to the TeamViewer chat session. It did not work, when I open it ask me to activate with Key#, he never gave me key#. So I'm super upset now. So I'm waiting for Mark to answer me, never dose. I get back to chat area for MinuteDownload, I'm number 6, it takes a good 35 minutes, and guess who is on the chat........ Mark yes thats right, he said we were disconnected, but we were not because he asked me questions that I typed  on the connection.

At this time I had  MicroSoft on the phone again to tell them the new problem and they recommend that I reinstall Office 365 back, so get MS ready to install it from ther end.  About this time the MS representative was in my PC and could see me chating with Mark. He said he could not give me a refund because he installed it personally. Then he wanted proof of it not being activated. He wanted to know if I installed the new Key#, my response was no because you did not give me one, so he gave key#and MS person said that Key# was invaild ( must have 25 characters it was only 24). Asked him agian to just give me refund and he disconnected me.

I'm Not able to conntact them now.
