Lack of knowledge

so yesterday, I went to Capitec bank to increase my limit and was told I do qualify, the lady who was assisting me looked very *********** if I can put it like that,i have a credit facility with Capitec bank but was told It is expiring on the 29/09/2017 so I wanted to re-apply and last month I was told I do not qualify because I do not have an account, I ended up opening a Mr. Price account now yesterday after spending an hour and hour by a consultant who is busy scratching her head, looking through the door, hut chatting and I am told the screen is grey what must I do as the client if the system is grey?what do I do with the system is greey,what is my business win that, I ended up out of frustration leaving and telling her that I have been at the bank to long wait for the system to ungrey.so please tell me what is the reason why I do not qualify when I am clean on debt and being assisted by an *********** person made me more frustrated not to lie, she knew nothing, with every page she is on, she would run to the manager and ask what must she told ,she would just stand up without even informing me where she was going, so not professional
