dotsure *****ing my money!!!

I opened an insurance with dotsure in 2019 October and I was informed by dotsure that I am supposed to have a netstar tracking device installed in my car due to their own requirement of which it is included in my premiums. I then cancelled my car insurance in October 2020, They sent me a cancellation letter by Monique Basson as confirmation. Early January 2021 my account was debited by netstar and when I contacted Dotsure I was told that ,the matter will be investigated and they will get back to me, no one got back to me until today.

Today I received a letter that shows that I owe Netstar R435.00 for the tracking device that I did not ask for . I spoke to Joanne Laow @ dotsure who advised me that the contract for Netstar is 36 months and I am liable to pay for it, even when the car insurance is cancelled before 36 months . I asked for her manager and Anastachia Windwaai the supervisor advised me that, she is still going to investigate the matter (by listening to the recording to verify if I was advised about the 36 months contract of Netsar when i was taking this insurance, I did agree on those terms , and also that I will be liable of the payment even though I cancel) and she will get back to me)

The below is what is written on dotsure car insurance contract : You need to have a Oakhurst Smart-Box installed within 14 days in your car on a month-to-month contract with NETSTAR which will assist with vehicle monitoring and tracking. The cost of the fitment and the monthly subscription is included in your monthly premium.

I want Dotsure to cancel this netstar contract ASAP!!! since i never took any contract with netstar! This is not acceptable at all !! this is **********!
