Dead service plan

I took service plan with absa in December 2919. This morning I took my car for service in the morning at 7am, their agents has been sending me from pillar to post just approve the plan. I called in 4times all their agents promise to come back to you in 30min, it's been 7hrs now, not one of them called to tell me what's the delay. My car is still at the car dealership without anything done, my day and time waisted.
