Bad service provided

I app**** for a revolving credit plan on the 31 March 2016. A whole week went by without any response so I decided to call and see what was going on. They asked me to send proof of employment which I did. Then Monday the 11th I decided to call again to find out what was happening as I didn't receive any feedback I had to hold the line till my airtime ran out(100 rands of airtime gone) without even being assisted. Then I called again Tuesday same story my airtime ran out with no assistant. Wednesday I bought another 100 Rand's of airtime and I called they again made me hold the line for a very long time. 10 minutes to be exact and the guy said sorry I can't get the loans department can u hold again he asked I said no. Just give me their direct number. I then called and again had to hold again than I spoke to a consultant who said ur application was declined. Honestly why wasn't I called or at least emailed did I really have to go though all that wasting airtime. This is truly bad service for a bank I've used for so many years. No this is unacceptable!
