wesbank insurance confirmation

i receive a call last month from Wesbank saying i needed to send the the confirmation of my car cover insurance, the lady i spoke with was quite rude and harsh. i told her my car does have insurance and i dont think it any of their business, she then told me wesbank does that annually of which i disagree as i got finance by wesbank in 2014 and i took my cover with my way which i then changed to old mutual. i sent them the proof of car cover insurance on 23/01/2020 but still they attempted to debit on my account on the 25th an amount of R1120 my car insurance is way less that this please someone help us to get to the bottom of this. something is not adding up
