Ignore, lie & deceive- After service moto.

I took my vehicle for a service on the 12th March 2015. All I asked above the service was to check my rear de-mister, Front drivers visor light and a vibration coming from the front right wheel. On requesting them to check the front wheel, they suggested wheel balancing and alignment. When I picked up my vehicle only the rear de-mister was attended to. The front wheel apparently had uneven tyre wear and the visor light was due to the visor which was on order. I took the vehicle to have the tyre replaced but there I met honest people, who balanced the wheel and good-bye vibration (no uneven tyre wear). Today, after hounding a certain Neville and the dealer principle I have not received my visor. I paid for wheel alignment and balancing which they did not do but are quietly sweeping this under the carpet. I have written an email to customer complaints- NO REPLY. I have phoned customer complaints (***) and still no reply. I tried phoning again this morning and cannot get hold of Neville or the dealer Principle, even by using his cell number. WHERE DO I GO FROM HERE!!!!! If there is anyone from this miserable brand of vehicle out there.
