Virgin Money sharing personal information and closing accounts without informing customers

Virgin money decided to just cancel all credit cards after 5 years of support without notice. When I called to hear what was going on they indicated the message must have gone to spam and they are migrating my account with all my confidential information to ABSA without my consent, Absolutely unacceptable. When I then asked to close the account they responded that I can't due to a pending transaction and I have to monitor my own bank account - not like they send statements so you have log in every day to see whether it's cleared. When asked to close immediately once cleared they refused as "it doesn't work that way" even though the account is paid in full. Poor Poor service
