PATHETIC SERVICE!!!!!

On the 21st of September I logged on to my FNB cellphone banking app, the app stipulated that i am due for a upgrade to platinum and a kredit increase! I then app**** to do so, for i needed to pay a deposit on my vehicle! After the application was successful they asked for documents to be sent through(proof of residence & copy of ID) for final approval and it may take up to 3 working days to complete. I sent through the documents on the 22nd of September of which FNB only checked for my documents on the 25th. They rep**** with yet more documents needed from me to complete the app. The proof of income I had to send, they only received today after I sent it again this morning! After that they said it will still take 3 to 5 working days to complete the application for my upgrade and increase! Not once did FNB follow up as I am their client, I had to contact them more than once!! I am very unhappy with FNB's service and would like it to be attended to!
