Accounts department ****ty

So I tried to open a 6month account at CNA so I don't need to pay for a PS4 cash. The store calls me to say their call centre said my company name and what is reflected on my bank statement doesn't match. So I went in-store to drop off my payslip and Mark on my statement my salary. I check in a day or two apparently I can not afford the account. I so puzzled how? I call the call centre and they can not explain and are so so rude. I ask a question and the call centre agent just keeps quiet so so frustrating. Honestly I have never missed a payment on my forshini account. I do not have any other accounts, apart from prepaid accounts...
