Cancellation request but NO HELP

One the 11 Oct 2017, i was phoned by a lady from Motorite about a service plan, but when rejected.. minutes later i received an email with the plan on my name through wesbank with my car finance.. On the 12 Oct 2017, i called wesbank putting a cancellation on the plan and sent an email.. sadly nothing was done and was just told it will be handled.. then on the 25 Oct 2017, i recieve my statement with the extra amount of R285 still on.. i sent another email and phoned and they said it is set as urgent.. but UNFORTUNATELY TO FIND OUT LATER through motorite that they only sent a Cancellation on the 22 NOVEMBER and motorite rep**** immediately.. then i phoned Wesbank but they kept saying they need a response.. only today.. 3 months later i received the cancellation.. i want my 3 months money back refunded or taken off my monthly premium as this is ridiculous!
