De*****ing & misleading clients

I bought a car yesterday and had someone by the name of Itumeleng call me to offer different quotes. I’m not sure how he got my number. He spoke to my husband and later came back to speak to me requesting my banking details. As an agent I was in contact with I gave him all he requested to activate the policy so my car can be delivered. He later advised, after concluding everything that he will be debiting my account with R950.00 to which I asked if he had disclosed this prior to speaking and making calls to get us insurance. He said it’s not his duty to do so. I asked to be transferred to the person whose duty it is and he said it’s no one. I was not asked affordability questions nor was I asked for my account to be debited. Nothing was disclosed prior to the service. The level of unprofessionalism that Itumeleng offered left me in awe as he even imitated me on how he was “suppose” to inform me of the charges. He said my query will be escalated but I am yet to receive a call. I even called to follow up few minutes ago and he was not available to take my call. I do not consent of my account being debited due to misinformation, shifting blame and non disclosure of information. This is de*****ing people and misleading. Holding on to information for personal/ company gain.
