Innovation group bad service

Based on the attached letter, even though i explained to the consultant that my car was in for service, the BMW Northcliff the service agent did not give me a report or spoke to me regarding any faults, my car was driving fine up until now when i've put in the claim for it not starting, however if this is still a problem i would like to be refunded for all my payments made thus far and also cancel my warranty with innovation group for the following vehicles, very disapointed in innovation group though by making a decision on a clients behalf to say that i knew about the pre existing faults where as i don't, I've also requested for proof that they gave me or mailed me the pre existing faults on the vehicle BMW 302i, they could not and also mentioned that the BMW agent no longer works at BMW Northcliff, I don't have the problem with BMW Northcliff which their service is awesome

Please cancel my warranty with immediate effect, and refund me the money that was debited from my account up to now, very disappoint customer Below 2 cars to be canceled and refunded immediately

1. BMW 320i CB34CHGP 2. MINI cooper (ID ***)
