Bidvest bad communication

I have received a Bidvest Service plan upon buying my car almost 2 years ago.

They have previously paid my services and I was told by the dealership that the service plan is 60 000km's or 2years (whatever comes first) with additional 40 000km's. I specifically went into the dealership to make sure that I do not miss my 60 000kms service, and was told its fine as long as I bring it before June 2018. On May 11 2018 I took the car for service, a few hours passed and I was informed that Bidvest is declining my service as it has expired on 40 000km's...which doesnt even make sense as my car was serviced on 45 000kms and they happily paid for that. I just think that they did not even contact me to inform me that the plan has expired or nothing and I have spoken to Bidvest several times about a scratch and dent policy I also had with them which expired and all was fine,. It is false advertising they have, as I received my car in June 2016 the policy should have been active still as I only reached my 60 000km in May 2018...

I would appreciate some clarity on this, as the consultant I spoke to was not of much help and made no sense at all.,...
