Trying to get simple problems resolved impossible

I've called and visited Nedbank so many times for the same problem and they still haven't resolved the problem. And it's very simple: take our old foreign phone Nr. completely out of the system, put my SA cell phone in so I can get notifications when we use our credit cards. Telephone customer service proved useless. They said I had to go into a branch to change or delete Tel Nrs. (which I had already asked them to do 2 years ago after we moved to SA and switched our account over). Now I've been to the Sea Point branch three times, waited in line and today, I even insisted on speaking to the manager. They assured me that this was taken care of. It still isn't. When my husband uses his card, it still doesn't send a message to our SA cell phone. I'm sure if I were to go to the branch again tomorrow, our foreign cell Nr. would still-once again-be listed on file!<br> <br> The system can only be blamed for so long. After a while, it's just incompetence and lack of customer service not being able to get such a basic thing done correctly, the first time. I have lost many hours waiting in line, visiting the branch and I am simply tired of it. If I had the energy, I'd move my accounts elsewhere.
