Poor follow up.

I have had the worst service this week from directaxis with regards to my loan application. I was busy finalizing my application on Friday when I had a query about something and they were going to call back. It's Sunday and I'm still waiting. I tried calling yesterday but used all my airtime up being put on hold with no success of speaking to anyone and finalizing my loan. I urgently need this sorted, this could have been sorted long ago had the follow up been better..
