Toyota stop harassing me

I recently bought a secondhand Toyota from Pongola Toyota

I have clearly stipulated on the contract not to get contacted for promotions or any other services.

I took delivery of the car on the 4th of August I get harassed for comprehensive insurance, life insurance, re-financing, extended service plan, even pet insurance, I stipulated to all that I am not interested, only to get contacted the next week, then I block the numbers and get harassed on my office line. Please remove my details from all of your databases I do not want to get contacted
