Regus failed to make change in credit card information then closed my account and accelerated 6 months of payments Washington, D.C. Nationwide

Regus provided me office services. I changed the credit card I used for automatic billing.  I notified Regus.  They did not make the change and instead canceled my account when the old credit card didn't work.  Then they said I owe 6 months of payments plus collection fees and wanted to charge me a reinstatement fee to reopen my account.  They are completely incompetent and outrageous scam artists.  I think they must be going out of business and are looking for ways of generating extra fees.
