Bad service, unprofessional consultants

Capfin wasted my time, i should have received money from a bank within 24hours. i went to submit every thing at pep store Chrishanni mall 21/11/17, they call me few hours after their line was bad they hanged up an never called back, contacted them they returned my cal same story of a bad line and no call back,been getting alot of sms that the app is in process and they will call once finalized. 22/11/ 17 i called them they return my call and finalize everything i was promised money in my acc before the 24/11/17 and i was happy with that on the 23/11/17 ,3 consultants called me to say they calling to finalize a loan told them i have already don't that but was told they will have to listen to their recording and call me back.. no call back spoke to they superior who didnt know what he was doing he said hell speak to their finance depart and call back nothing until i call them 24/11/17 morning to cancel the loan as i no longer need cash. but later on the day an sms came that everything is finalized and money was deposited i asked them to reverse it they said they cant, i needed money on the 23/11/7 and as per capfin false advert i was expecting money within 24hours. my question is why are they giving out false information and adverts to gain clients i believe they using people because they know they in need of cash. i can sue them for what they have done and i miss my flight because of them and their inconvenience
