Cancellation of clientele policy

I was recently ******* by a clientele sales person to join the client funeral plan. The lady said we only were checking to see if I qualify for the policy and that I'll be soon contacted by clientele to tell me more about the policy and to confirm if I'm interested, then afterwards, I received a message from FNB saying that I had authorized a debit order for 23rd of December 2021, informing me that they (Clientele) will debit of R250 without my consent. I tried contacting customer care service with no luck. (I waited until my airtime finished and your people don't even call back. I don't want a policy opened **********ly. I do not know what you teach your sales representatives but this is *******.. I want the stupid policy closed and ergo, the debit order cancelled as well.
