Disgusted about Cartrack coerced scheme for additional benefit without consent

I have three vehicles insured and have 3 contracts with Cartrack, per NGOZ000142. I have been honouring my monthly subscription, until I received a call about activation of road assistance and downloading of an app with no additional costs, few day later received notification of installation which I did not give consent on and further debited my account. I refused such and hoped that customer service as they claim will look at the matter, I’ve received interchangeable call before 08h00am or after hours, day after day I receive calls, if it is not accounts it’s client services, what a disgusting service and will take up with other ombudsman scheme
