Unacceptable service from the Loan Department.

I'm very disappointed with the service i received from the loan department at FNB. I've been with FNB for years now and the way i was treated was despicable. I did an online application on Monday on the App and before i even finished, i received an sms saying that i do qualify for a certain amount and one of the consultants is going to call& assist me finish the application. I waited for the call and until Tuesday after 12pm, when i decide to give them a call i was taken from pillar to post and nobody was willing to help me. Some of the consultants that i spoke to kept on telling me that the system is down and they are working remotely. What really frustrated me is that after making me hold for a more then 15min they will just hang up on me....such disrespect! I called again today to try and get assistance still nothing happened, when i was calling back for the third time that is when i received a text message saying my application was unsuccessful which i do not understand& believe because the App showed me how much i qualify for, and which the sms stated as well....is this how FNB treats their clients now?
