They always say it will take 30 days. I've had issues where it really was resolved in 30 days. Most times, no, so I call back. During one repeat call, the agent told me they are instructed to say "30 days" but in reality it's longer. She said, call back in another 30 days. Before the second 30 days was up, the issue did get resolved. Don't expect to hear from them or to get an explanation. I still have an issue with a 2020 return that isn't processed. On my last call, the agent said "yes we received it, we see there was a refund for xxx and we agree with the refund but haven't sent it." To which I said, that is why I'm calling. He told me he'd put in a "referral" and to wait 30 days. It takes many tries to get through but I keep trying and eventually get through. Once I'm in, I ask them to please not put me on hold, to mute me instead because I've been on hold and gotten disconnected. They are agreeable to this.
