Have I been haked/scammed?

Over weekend received what looked like official request from Microsoft to add second layer of security to my email.  I followed instrutions-their code sent to husand's email automatically(didn't put it in). I have called(just awhile ago) and emailed to get my iphone email access to work.  Gave me go.microsoft.com/fwlink?Linkld=277093(text) to make it work. Just called 18552244648 from Microsoft(looked up online). They directed me to logmein123 etc. Wanted to charge me $69.99(Adam Sandler) to fix this problem. I am baffled. I did not ask for this. I didn't want this. Why should I pay for this? How do I fix it? Is this a scam?  Gloria Solorzano
