Refuse to cancel my application

I did a loan application at about 18:37 on my phone yesterday and immediately called Finchoice to cancelled the application. I was then advised cancellations can only be done by the “Enquiries Department”. After speaking to numerous consultants and being transferred from department to department my request remained unsolved. The following morning (30.01.2020) I contacted Finchoice again at 7:33 seeing that this was an urgent request and did not want the money to be paid to my bank account ,then I was told no you cannot cancel your loan application. After 8 telephone calls I could still not cancel my loan application. I then requested to speak to a manager, however the consultant insisted on dealing with the enquiry. Never in my life have I received such horrible service to say the least, for something so simple as cancellation. As a client I am sure I have the right to change my mind and or requested a cancellation. I will definitely be taking this up with the Consumer Ombad.
