Maintanance plan

So i contact your Ford Protect Call Centre to inquire about premium care warranty. I get offered a Premium care mantance plan for R1138 per month after i have told her my Everest is on 116000km. I tell her that i will contact her today to confirm the deal. ..... Today i phone and the criteria is 105000km and i dint qualify anymore. I tell them to go listen to the tapes and come back as the lady made me the offer. They do that and come back to me and say sorry cant do it the criteria is 105000 km. How to someone that represents a company like Ford make a mistake like that and a customer must just take it as a mistake. How about honoring the deal your employee made and take the knock instead of ****ing off another client....
