My name is Patrick ID no

My name is Patrick ID no. ***. I received a call and accepted that they must install car track on my car. I agree. They install it on the 15.10.2021. Only to find out I dnt have a CAR WATCH and when I call them they say I must add R21.00 for car watch. On the 19th, I told them to cancel my package they say I must pay cancelation fee. When I ask them for the manager they just play songs on my ears. Regards Mutshena ***
