Failure to Deliver on Sales promises

I purchased a 2018 Ford Ranger from WeSellCars in Durban (Nandi) in June last year. The actual experience was initially very positive. While going through the purchase process I specifically asked if the vehicle had a service plan as this was a pre requisite for me. I was told in writing that the vehicle had a 4 year 120,000 km maintenance plan. I am now trying to take the car for its first service - and the dealer is saying that there is no maintenance or service plan.

The Sales lady I dealt with (Shireen) has since been moved from Sales and I have been promised multiple times that that her manager (Angelique) will be in touch to discuss the issue - and 5 days later im still waiting..

A maintenance plan has a value attached to it and I was told that this was included in the price I was paying. Either this needs to be resolved with Ford - or I need to be reimbursed the value of a 4 year, 120,000 km maintenance plan that I was told I had. I do hope that this is resolved soon so that I can amend my rating and so that I do not have to escalate to the motor ombudsman to report this.
