Bad customer service B+M Ford Bredasdorp

We take out a extended guarantee/ warranty on a Ford Ranger at B + M Ford Bredasdorp. We phoned them yesterday regarding the extended guarantee no one could assist us. We phoned the owner Mrs Steenkamp she said first thing tomorrow morning she will phone us back with a speaker call with the technician that we can arrange what we can do about our bakkie. We can drive with it apparently it is the gearbox of the bakkie. We paid for the extended guarantee now when we have a problem no response.
