FNB Home Loans Unprofessional Service

I am a current FNB Home Loan Customer and app**** for a readvance more than 2 months ago. It was approved quite quickly but in order to receive the payout they needed to verify a few things. I was asked a few times to submit more documentation and then they needed to verify things with my wife, the person who does this would phone and if she was unable to answer would phone a week later, then try a week later again. The questions asked were things I knew but not necessarily her since I am responsible for the account. When she asks him to call back he doesn't, really really delayed processes and unprofessional. I logged a complaint on the 13th May and am still waiting for someone to contact me. Really terrible. The Private Wealth consultant has also not helped at all. Very delayed.
