FNB cannot keep promises or accept they messed up

After 3 weeks of up and down...being approved for a credit card, signing 4 different agreements and quotations and being promised delivery of my card 3 times....still nothing is happening...they requested 3 payslips...which i submitted....they requested that i sign a quotation once more...i did it...and now...after all these approvals...and acceptance of my payslips...i get told they need an ITA34 to verify why my income was R6000 more in February...which is obviously because I am a commission earner...and that a person named Mozwanele or whatever messed up...and they cannot give me a credit card...this is completely useless service. Which i have been experiencing from 2015...and yet they still do not fail to disappoint...once again...fnb is the worst and i will make sure every person on social media knows it...i spend a 1000 rand a month on bank charges...yet they still lie to me without even batting an eyelid.
