Trying to open a bank account for 6 months

I am trying to open a bank account for our Trust from the 24th of August 2017. This is now six months later and still no bank account. I have send all the necessary documentation, but I still receive emails saying that I have to sent the Completed Appointment of Administrator document which is attached. This is now the 17th email that I send saying that there is no document attached and that I have already send that document in November 2017. They want a trustee to sign the document that is no longer a trustee, we already sent the RESOLUTION where he resigned several times. I have spoken to Thabo on the 14th of Dec 2017 which he confirmed that FNB has received the document and that they will send my account number asap. I then spoke to Usna on the 12th of January 2018 Ref nr ********** 4 which she confirmed that all is in order. I then spoke to Jenifer on 18/01/2018 which she said she will email another document, but still the same document which we already sent. Then on 23/01/2018 I spoke to Ntambi Simka where she said that there is another document to be signed, but we still haven't received it. Is this the normal practice from FNB or is it BAD SERVICE????
