Terrible Service

Good day

Nedbank made me an offer to increase the limit on my credit card. I clicked and the amount was available the next day. When I tried to transfer the amount to another account it rejected due to validation. I phoned in for assistance. The first person picked up and placed the phone on their desk. I could hear staff in the background. I dropped the call and phoned again. The 2nd person transferred me to another department without informing me that this is what she is doing. The 3rd and 4th person also just transferred me to another department. The last persons' line was so bad. I could not here anything. I was on the line for 20min plus. No callback from Nedbank and no assistance. How can this be the level of service that we receive?
