Company Registration through FNB troublesome

In 2018 I opened a bank account with FNB for my business and they assisted in opening a company as well. I received the company registration number and some of the documents. I was unaware that there are documents I will need later and when I tried to contact FNB to assist me getting the documents, they just answer I must ask my accountant, and the accountant says I must get it from FNB. I am urgently looking for the following documents if anyone could assist I would be truly grateful 1 - Memorandum of Incorporation COR 15.1 & COR 15.1A 2 - Notice of Incorporation COR 14.1 & COR 14.1A I have tried quiet a few avenues to try get the documents but was not successful as they all say I must get them through FNB Hope for a speedy reply so we can settle this!
