Lies and poor service

I took in my car for service on the 20th of November 2015 @ Vw Bryanston. When the dealer called 360 Plus they were told my policy had expired. When I took out the policy I specifically mentioned that I would like my plan to kick off at a specific service interval as I had already paid and took in my vehicle for that particular service interval they wanted to start it at. Today I'm being told that my policy has expired and they have no records whatsoever... I spoke to Theodorah on the 23rd and she promised she would get back to me by end of business, she never did. She went on leave without getting back to me. I spoke to another lady who also promised to take over also she never got back to. I find very unprofessional of the staff to tell lies number 1 and to keep transferring calls from one department to another.
