Ford Bruma Scam on Extended Service Plan

I bought a Ford Ranger bakkie at Ford Bruma in July 2019. Amongst other benefits, I was told the bakkie had an extended warranty up to 150000km of July 2023, which ever comes first. I did my first service under the Extended Service Plan without issues. However, when I went for the second service I was told the Extended Service Plan only covers one service. When I asked why was I not told, the sales guy told me he didn't know. At some point during the purchase, the Financials lady sent an email which state the 150000km and July 2023 as my terms of Extended Service Plan, there is no mention of one visit.
