Frustrating work from home inbound callers

I am extremely shocked at how the call centre is operating, supposed to be a world class company yet it takes us 5 days to try and resolve 1 query. Spoken to 17 agents and still not resolved. When I say 17 agents, 13 of them we can hear perfectly but they can't hear us after been transferred by customer service. Apparently they working from home. Yes it's a toll free number but what a mission to get one thing solved. I'm so disappointed in this company. I eventually put the phone down in the agents ear because after 48 min on a call and this 6th person wanting to transfer us again, just list it. We had trouble at the branch, took us 3 hrs to open an account. Then call to the control centre since Monday 23 October 2023. Today Thursday and things are already just a mess. Don't get me wrong, grateful that Nedbank reached out when we were in trouble and helped us, but we had to call back to finalise things and change debut order detail. These past 2 weeks has been a blessing but a huge nightmare at the same time. Fix your home bound call centre people or get them back into a call centre environment again as it's not working, I can promise you that.
