Difficult to get a Homeloan :-(

I've app**** for a homeloan at FNB and it was approved. It's currently at their attorneys and one of the requirements are life assurance. I don't have sufficient life insurance for the mortgage bond and need to apply for FNB's MPP option. I've tried 3 times to get hold of the correctly department just to opt for the option. If I phone the homeloans department then they **** the call once someone picks it up. Someone from FNB phoned me last week and told me that someone from the MPP department will get hold of me and none have done so thus-far.
