Annoying service

Once again I have to query additional charges on my account, I have been charged R175 maintenance fee and am still awaiting feedback from you guys. Please just give me my money back..I have already paid my maintenance fee at the end of the month, now I have an additional charge of R175? I am not happy with your service..because I have to constantly query things, if my banking app is not off for days, or you have switched off the ability to get an old proof of payment on the app, and now its additional charges, or my surname has been changed back to what is was, Or I have to pay interest for heaven knows what, or a fee is charged and then a different amount is reversed...Please get your act together...
