Worst Service and very ***********

I am so disgusted by the unprofessionalism and incompetency. I cancelled my policy about two months ago and have send the ID copy and registration number photo, which is even ridiculous that they request this information, but clearly this still has not been actioned as I still receive calls from diffrent constultants asking me about the premium and that my account will be deducted, what does it take for this company to process a simple cancellation?
