Not satisfied with the service

I have app**** for a loan on finchoice but they are not telling me if I qualify I was told they would get back to me in 24 to 48 hours but it has been a week, I am at a stand still now as I am waiting like a fool, I call them every day only to be told I will be contacted and that my loan is being processed, this has caused stress and sleepless nights because I only app**** with finchoice now if they reject my loan where am I going to get it, they must stop lying telling us to wait 24 hours where else they don't keep their promises. I will escalate this with consumer tribunal as this is unfair
