Horrid experience

I've been insured with MVIA for 2 years and never had issues, my woes started when I sold the car they had initially covered and bought another 1 which they insured. At POS, I advised the Sales agent that when I bought the vehicle, it didn't have a logbook therefore I can't confirm the services of the vehicle, he understood and activated and advised that in 4 months I could claim as I had done with my previous car. Fast forward to month 5, I request to log a service claim, they start taking me from pillar to post and I'm being told that I can only claim after 12 months whereas the waiting period is 4 months. I had to put my vacation on hold all because of the service I wanted to do before going on vacation with the family. This is the worst experience I'm getting and really regret going with and believing what the Sales agent said.
