Disgusting Service after 20 years of Bond payment

I had my last bond payment done in May 2022. Went to Nedbank Table Bay Mall on 18.May and asked what the next step is. There was an amount of R59.00. Was told this is to keep the bond. I didn't want to keep the bond and paid the amount right there and then. They told me, in order to cancel the bond I have to call the Nedbank Call Center which I did the very same day, 18.May 2022. A call center person, Theoline, took the call and explained, that Nedbank would nominate a law firm for the cancellation and that law firm would then contact me within seven days and send me the title deed of the property thereafter. Nothing like this happened! On the 31.May I phoned the call center (cannot remember the name of the agent) and explained again. That female also promised the same, that a law firm would contact me, cancel insurance and the bond. Today is 30.June and nothing happened. So, phoned the call center again. Some female agent, Tebogo, looked into it and told me that there is now a balance. I told her that there was no balance when I tried to cancel on the 18.May. She explained balance is because of insurance. She did not listen that I explained that there was no balance when I tried toi cancel the bond. She promised that the first agent, Theoline, will call me today. I am almost sure this won't happen. Disgusting service from one of the big banks in South Africa after 20 years of bond payments. Think twice before doing any business with this bank. No surprise that all the big banks a currently sued.
