No feedback or response on my query

I app**** for a loan with Finchoice on Dec 30 2017. It was approved l,however i changed my mind after calculating and seeing that I will be paying almost 80% interest. I phoned Finchoice to cancel on Saturday and I got a gentleman who said he can't help me and gave me a number to call, I did that and I got no answer. On Tuesday but 02 Jan 2017 I phoned the number again and there was no answer. Ive also sent emails and WhatsApp on yheir WhatsApp number and still no one attended to my query. This Morning Wednesday 03 Jan 2018 I woke up and I found that the funds have been pain into my account. I don't understand why they are so quick to attend to us when we want to apply for the loans but NEVER attend to us when we want to cancel. I am so stressed, I don't know what is supposed to happen with the money in my account because I don't need it.
