Disgusted with Outsurance

I am disgusted with service i have received so far from Outsurance and i will make sure i never recommend anybody to this insurance. Their service is the worst ever. I joined Outsurance on the 14th of December 2018 and was debited on the same day that was fine. I spoke to the sales agent to check if i could change the debit date to the 25th and he said yes, he did not indicate there would be pro rata fee. I then called on the 8th of January 2019 to ask them to change and they agreed to do that. They then said there would be a fee of R560 but i did not agree to that and they went on to debit my account without my consent. I then asked for the recordings of all calls but up until today i have not received anything from outsurance. Yesterday i spoke to the team manager who promised he would call by C.O.B but still nothing has happend till now. I am really angry and will take the legal route, because they cannot just go and debit my account without me agreeing to that.
