Doesn't respond, cards and all users are deactivated but we continuously have a balance.

At first, Navan (TripActions) was amazing. Managing company expenses internally became easier and faster. However, we felt like it had too much for us. We tried to leave Navan, turned off all our employees physical cards and deleted every user account except for our accountants and C-suites. After we requested to close out our account, we never heard back despite reaching out 4 times. Then we started seeing charges to our employees' cards that we had deactivated. Does it make sense that deactivated cards are being used to make thousands of dollars worth of transactions? When we addressed this issue, Navan said our account manager will be in touch (who was supposed to be in touch when we requested to close our account). It's been 6 months since we first requested the close and we still haven't heard from anyone; our cards that are "deactivated" are still seeing transactions even after we removed the cards from every vendor. Please use another provider such as Brex for your company.
