Service plan policy only applicable in Hatfield

During the last week of December 2015 I called in for an appointment to service my car at Lindsay Saker Welkom, I got an appointment for the 07th of January 2016, then on the 06th the day before my appointment they called me shifting my appointment to the 12th January 2016 due to the fact that they were overbooked , on that phone call I was asked how I will pay for the service, I mentioned that my car is still on the service plan, then I was requested for my service plan policy number I then I said I will email the service plan policy to them. Upon receiving the service plan policy they responded on email\ Unfortunately this is a Hatfield service plan
