Multiple AVG accounts

I have been a customer of AVG since 2001.  Over the years, I have been through multiple computers as has my wife and, reviewing my accounts, today, I seem to be paying for three active AVG Tune Up accounts.  One is a multi-device account which renewed, automatically this September, The second is for a single device which renewed, automatically, this month, and the third account is for a single device which renewed, automatically, in November.
     My wife passed away three years ago and her previously covered PC is no longer in service.  Obviously, I don't need coverage  for it.  And if the multi-device license really does cover my desktop computer, a new desktop computer, my phone, my tablet and my lap-top, then I see no need for a second single device account.
     What I would like to do is retain the multi-device account, get rid of the other two single device accounts, and, if possible have some refund from those two accounts applied to the multi-device account.  How would all this be possible?
