No service history for my vehicle

In September 2017 I purchased a car from autopedigree and after weeks I realised that the buttons on the steering wheel are not functioning well.I then took my car to a Ford dealership so that they can repair it as the car is still under "warranty" and they told me they can't help me until I give them the service book that highlights all the service history of the car.i called autopedigree and I was given the regional manager's contacts and Email address. I sent the manager an email I'm December. His reply was he is waiting for the manager to retrieve the information and they'll get back to me.Up until now I'm still waiting. I'm not enjoying the car at all.because it's due for the last service and I don't know if it will be serviced for free as it's still under warranty or I'll have to pop out money to get it serviced.I feel like I'm not getting value for money services that I deserve.
