Bad Client service/ Irate Client

I just recently got vehicle financing from Wesbank for over a week ago. On Tuesday 03/09, I received a call from Thandiwe Zwane (from Wesbank engine room). Upon my call with Thandiwe she advised that I have not actived a product that was part of the contract, I listened to her and informed her I was under the impression that the car dealership had activated the product that I and the car dealership agreed to activate. However if she is saying my car dealership did not activate the product that both parties agreed on then she can activate but I will get in contact with my dealership. She then told me she will activate it then, I immediately contacted my dealership after the call and only to find out Thandiwe is offering me another product. Yesterday (04/09) first thing in the morning, I sent Thandiwe an email requesting the cancelation of the product she positioned. Thandiwe then responded by "she has been trying to call me with no avail:, "when can she call", I responded with you can call me now, indeed she called and I expressed that I do not require the product and I am canceling, she sounded disappointed but promised me that the CPP cover will be canceled. I asked her for a cancelation letter, she responded by saying I will receive the cancelation letter. I have not received the cancelation letter instead. I received a confirmation letter of the product take up. 05/09, I sent her an email she did not respond and still have not responded. I have called Wesbank more than 2 times today, I was firstly informed the cancelation will happen after 30 days, I expressed "I cant wait 30 days", then I got transferred to the cancelations department and no one answered my call. I called again spoke to a lady by the name of Precious who informed me that the CPP policy is not yet activated she is sending an email to the cancelation department to stop CPP activation and that the previous day Thandiwe sent a request for the product I took with the dealership to be canceled not the one I requested to be canceled. I asked her to please specify that the product I am not taking up is CPP. Then I received a debit check mandate of an installment that is including CPP. I am not impressed or happy, who should pay for a product that they do not need. I work in a client service environment and this is not service at all, I also have targets but I listen to my clients' requests. No response from Thandiwe or the cancelation department thus far, this is frustrating and unprofessional at all. First time using Wesbank and I wonder how the relationship will be going forward.
