Service plan

Bought a car from Kia Hatfield, the policy was sold to me incorrectly the FNI Mpho captured wrong kilometres which now the dealership doesn't want to amend the policy, Nela from Liquid Capital worked out a quote that I have to pay the difference if I want to continue with their services hence the dealership doesn't want to amend the contract. As I want my car to have a service plan I opted for payment plan Nela from Liquid Capital said no arrangements can be made the money must be paid in full
