Nedbank - Frustrating and ***********

We have a flexible home loan with Nedbank. We wanted to withdraw our additional available funds as we have paid extra over time. The home loan was linked to my Nedbank Money App at this time. I then got told I can only transfer money if I have a Nedbank Cheque Account(Which is Stupid). I then opened a new Cheque account( which I could not do on the online platforms as it did not work and had to call and it took more than an hour over the phone). Once the account was opened my home loan was no longer linked to my profile on the App. It took another 3 hours on the phone with Nedbank for someone to tell me that because we have a joint home loan we(me and my wife) now have to go into a branch(again WHY?). Now we both had to be there at the same time which again is ridiculous. We finally managed to do so and then when we got there they were OFFLINE. So we had to go and do it again later. After we did this, when I opened my App I saw there was a loan now linked to my account, but it was not mine. THEY LINKED THE WRONG PERSON'S LOAD TO MY ACCOUNT!!! . I phoned them again and got told I will now have to go back to a branch to fix this. This is so frustrating and I cannot believe they gave me access to someone else's loan and details. My overall experience with Nedbank so far was just Frustration and waiting and nothing ever works. The level of incompetence is just mind boggling
