Bad approach and service in guiding the customer!!!

Bad customer service received from Karabo and Dolly Took out a service last year, and was told that I need to pay 4 consecutive premiums, then they can pay for my car service. Took my car in Feb as the plan was now activated. My mileage had obviously overlapped during that time, and they told me it is ok since my intervals are 20k. Today I call them, my kms have overlapped as my car only shows you trips total and not the mileage, explained to them and they said claim won't be approved because this has happened before. The audacity from Dolly to tell me that it was out of goodwill!!! Asked other alternatives, there's no proper guidance. I canceled the policy right away
