***** on my account

I have been to diepkloof square branch trying to explain that I don't understand the transactions on my account a couple of times. Most explaination I got wasn't making sense. They said its because I was using the banks credit. Since I lost my phone I couldn't track anything on my account I tried the statement but the amounts where not making sense. The whole we I've been at the branch trying to get my app activated on my new phone, if it's not my fingers prints not working it's something. Tonight I got massages from the app all of a sudden it's working and someone is ordering uber eats and maxing my account
