Misled by dealership

Good Day I am so angry writing this review. I bought a car in November last year from We buy Cars Port Elizabeth. The sales man as well as the lady that was assisting with the finance of my vehicle told me that the car had recently been serviced was still under manufactures warranty as it was below 30 000kms,just over 15000kms. Today I tried to call VW to book a service and they just advised me I have to pay for my service. I asked the sales consultant,and he told me to contact VW as he is not sure. Someone please fix this ASAP
