Not catering for my individual needs as explained from the start

My vehicle is insured with MiWay, the general service of MiWay is very good, I currently have a problem with the company not being able to assist me with a border letter for my vehicle. They gave me a border letter for 24 January to the 3rd February, which they did tell me telephonically I can just phone every month in order for them to send me a new letter. Now when I have asked them for a letter last week , now all of a sudden they don't cover for more than 30days. My daughter is already in Namibia and not coming back for at least a year and being the 4th of February already this means the vehicle is uninsured at this stage. Nobody gets back to me regarding this , I did also ask them to trace the recording where the consultant told me to just ask them every month. If I knew this before hand I would have used a insurance company like Hollard that does cover for a longer period. Really very unhappy about this !
