Why cant Standard Bank Home Loans be reasonable?

I have app**** for a re-advance home loan via the standard bank call centre, they have the incorrect phone number for my employer in their system and refuse to accept this and look on the Internet to find the correct number. I have been waiting for 2 months now for them to respond and keep getting the run around. the worst part is that the customer service folks don't even respond to my emails. This is just unacceptable service! Why wont the bank make an effort to at least contact me? Their ***number is the only way to contact them! I am your customer please have the decency to engage with me!!!
