When is discontinue QuickBooks 2021?

This is false information being posted.  A one time license of Quckbooks Pro 2021 IS NOT available for purchase.  this is per QB's support chat, and phone conversation May 25, 2022.  I have paid for 2021 twice, under the impression I was buying the one time license.  I am now told not true, and if I do not pay another almost $400, I will be cut off of ANY access to information in my desktop version that has been in there through QB's since the 1990's.  I have been trying for months, through the community, email, chat, and phone calls to find this one time purchase option.  Representative Kevin said yesterday that this information was false, and it NOT available for purchase.  Ridiculous!
