I need to settle my loan account

I've been trying to settle my mobi money facility. I called in yesterday and spoke to someone from their collections department and made an arrangement to have the settlement amount debited today, but it still hasn't been. Each time I call them I get cut off when they put me through to collections to follow up. Looks like no one cares to help me, and I need to settle this amount so I can get on to my other financial commitments. I've spent so much on airtime calling over and over again. I must say I'm very disappointed in their service this time around, I honestly never want to use finchoice again, I'm very frustrated. They're usually so helpful and efficient I just don't understand what's the problem with them today.
