Struggle to open account

I recently tried to open a savings account at Capitac bank in Queenstown. They said I must bring a proof of recidince and my I'd. I got a proof of recedince from our local munisipality and went to open an account. They then told me to get a statement from the bank where I bank at the moment. I got a statement from the bank and went back to Capitac. They then said that I must get an account with my adress on the account. I then took an account with my adress to the bank. They then told me that I must rather bring a letter head with my adress on. I went to the bank about 4 times and to two different branches in Queenstown. Every time I did what they Asked and still they managed to find a problem with the proof of recidence. I know with Fica there must be propper proof opf recidence. I haven't struggled half as much with opening an account at other banks and I am sure the requirements must be the same at all the banks. This is poor service and if that is how things work at Capitac I am not sure it is worth it to open an account with them.
