Trying to cancel extended Warranty and Service Plan

On the 18th October 2017 I sent an email with all the necessary completed cancellation documents to get my extended warranty and service plan cancelled. I phoned their cancellation department the following working day to ensure the email was received. I was told by the 21st November everything should be wrapped up. I have spoken to Khokela, Lwando and Lerato (latest conversation on 24 Nov) where i was told the Service Plan cancellation has gone through but she is hoping to get the Warranty cancelled by the 24th Nov. Ive now been informed that the money will be credited in 10 to 14 days. So in total I must wait around 40 days (from start to finish) to get 2 simple items cancelled. Not once since I sent the email to cancel the warranty and service plan has anyone even bothered to phone me back to back to give me any feedback. Yet every other day someone phones me to ask if I'm interested in getting an extended Service Plan and warranty for my existing Toyota!! This needs to be resolved ASAP before I even look at getting further plans
