How has your experience been with Fidelity's customer service when resolving account issues?

I've been a Fidelity customer for a few years now and have had a couple of experiences with their customer service, both good and challenging. Recently, I encountered a situation that required assistance, and while I appreciated the support I received, it made me curious about others' experiences. How responsive have you found Fidelity's customer service when dealing with account issues? Were they able to resolve your problem promptly? I think sharing our experiences could provide valuable insights for newer users and help us understand what to expect when we need assistance. Looking forward to hearing your stories!
