No response and bad customer service

I sent an email on 24/02 I followed up on 27/02 as I received no response. I received a response on 29/02, (no apology for the delay). Only half of my request was responded to, I emailed back thanking them for the info but requested that the rest of my query be answered. Palesa Selepe emailed back, who didnt even bother greeting me back, but advised that I should ask the Vehicle finance regarding my query. I would have thought that at least if they couldnt be bothered about my query that I would be provided with the contact details of the Vehicle finance department, this was not the case. Basically it was not their department or problem. The next day I received another email from Palesa Selepe with the exact same info that was previously sent! I responded a few days later explaining why I needed the info and why it was important for me to have these details confirmed. This was 5/03, I received no response, again on the 8/03 I requested an update, no response to that either. And again on 10/03..... still no response. R2957.84 per month might be nothing to Nedbank but its alot for me to pay a company who cant even provide basic info to their customers upon request!
