Acrobat has lost my account

Adobe Acrobat has lost my account.  It askes me to buy the product again.  

I purchased a license in September 2015.  I have not changed computers.  

I attempted to call the customer service center, but the connection was very poor and I was eventially disconnected.  Unfortunately, the customer service respresetatives were very muted and kept cutting in and out.  

I would appreciate if someone could help me.
