Bad Customer service

On 3 April I received a call from FNB regarding a credit card application. I was told by the consultant that he would send me a text message which contains an email address to which I need to send my documents, however, the email address did not work. I then called the number and was on hold until my airtime exhausted. The next day I found an email address online which is ********** to which I also received no response; I then called again and was on hold for long once again. I went online to lay a complaint to which also NO REPLY! This is ridiculous! I was given 5 days to submit my docs else my application would be invalid, yet, none of your emails or contact numbers are helping! Can someone sort this out ASAP please. FNB has already issued an enquiry on my credit report and I don't want this there in vain. Sort it out and email me back. Thank you.
