Very poor service for a highly ranked bank!

I had app**** for a credit card & loan on the 2nd of April. All documents were sent as requested on Monday 4th April. Security check was done and passed by the 7th of April. I was then informed that they were just waiting for my salary to reflect. During this time the final validation of my credit card account was done, activated and I had received my Credit Card. when my salary was in my account I had only received my loan and not my limit on my credit card. 7 weeks later and I was told they had to cancel my application and in proof of an email forwarded to me by the credit card escalations team stating that there was a system failure. Therefore they had to re-apply. I gave the go ahead and they had responded with " the application got denied" yet I was approved the first time round. they then said they will do a manual reassessment which till today I have had absolutely no feedback on . Every time I contacted FNB during the 7 weeks, I was told many times that i've been approved, and everything is done and completed. All we were waiting for was the limit to be added. STILL nothing has been done. I have been informed by the Team Leader of the branch near me , that this IS FNB's fault and therefore they NEED to fix this. But yet I am still waiting. They have sent me final agreements of the credit card and its debit order. I have also had 2 PLOANS added to my DebiCheck mandate for the 25th of May, but once again , I have not even received 1 of those 2 Loan applications. only received the PreAgreement . FNB best be getting this resolved ASAP otherwise I will be left with no other choice but to go through the ombudsman.
