Nedbank Homeloans - Never gets back to you!!!!!!!!!

Nedbank provides a service where they will call you back in 48 hours and its been over a week now and i really need to speak to someone. Called Nedbank and was number 157th in the queue and need someone to get back to me. Ive emailed them over a week ago as well and followed up again but no one gets back to me. This is the worst service i have ever had as Nedbank provides non workable solutions...........
