STANDARD BANK HOME LOANS FRUSTRATING SERVICE!!!!!

I don't know what else to do but to try get the attention I deserve here. I emailed Standard bank last week for a tax certificate to the email address provided on their website and copied customer care in. The email to the home loans department bounced but then a day later I got an email from customer care to say they have passed the request on but I must use the correct email address for this request which was the exact one that had bounced. I still did not hear back after a few days so I emailed the customer care again. Still no joy so this morning I CALLED and held on for 10 mins before the call was answered. I then requested the certificate I need from the consultant, answered all the security questions, gave all the details then he said if I wouldn't mind holding on. I then listened to music for another 15 mins before I put the phone down as I was on my cell!!!! I am STILL waiting. What more must I do to get assistance from Standard Bank Home loans???????
