No Agent Can Give Me Info, Only Response Is To Dispute A Charge I Can't See

Genuinely the customer service on the chat via the app is the worst. Not even mentioning the time it takes a rep to respond, but I feel like a lot is happening on my account I'm not aware of. It was resolved, but I was told I had an outstanding EDR authorization and what bothered me is that no one could tell me what it was for especially since I hadn't used my virtual card in a while. Even though I got my money back as a ticket was created very quickly, what worries me is no one could tell me what it was for after speaking to multiple agents. The only response I got was to dispute via a ticket. This is worrisome if something is being charged, I can't see it on pending transactions and no agent could tell me what it was for. Feel like I need to keep an eye on everything now.
