Non delivery of service

I made contact with the Dial Direct claims agent who sold me dreams and went AWOL on me when i made follow ups on service.I was using a rental car which can only be loaned for 15days realizing that i was going outside the country and wanted to save on days since i was not aware on when my car will be ready from repairs.I made a request that i hand in the car in the meantime i was outside the country and save on about 6 days and upon my return that i may then exhaust the outstanding days the agent agreed ..But to my dismay when i got to Europe car which is a service provider for dial direct the rude assistant checked me on their system and responded by saying the car is not reserved and will therefore not be able to assist me i was annoyed looking at the fact that i made prior arrangements to avoid such a disappointment..To date there's been no call or email from this non service even when i have made them aware because customers do not mean nothing to Dial Direct only numbers matter!!!
