Financial adviser refusing a client for cancellation

I am very dissapointed with my financial adviser Khohlula in Limpopo.he advised me 2join a policy on Friday on the 20/03/2020.i called him 4 cancellation in the morning on the 23/03/2020.but he continued submitiing my applicarion.on the 24th i got a message from my phone that tells me that they thank me for my application.i called him again on the 25 to tell him my frastration.and he tells me i need2 go2 a brunch and that his not responsible for cancellations.such treatment is very dissapointing
