Terrible service NO Help!!

I recently app**** online for a new home loan, with fnb , with whom i bank with. Its been almost 2 weeks now and ive made endless phone calls , using my airtime, holding on the line for nearly more than 30 minutes at a time only to be transferred from one department to another. I've managed to get a hold of a consultant who has been handling my application, Themba Kkambule, He has been no help to me at all. His line keeps ringing and going to voice mail. After laying a complaint his excuse was he tried getting a hold of me on numerous occasions which is false as my phone is on and with me at all times. I need to find out the outcome of my home loan and status of my application and I am utterly disappointed with fnb service. I am considering switching to nedbank because they offer a way better service than fnb. Also on the same note fnb has not been updating my payments and it is showing a negative impact on my credit status. I need all of this to be sorted out and if there is no feed back i will take this complaint further.
