Poor incompetant service!!

On Monday I phoned and spoke to Phalisa, she took all the new details for the car I bought, I told her that I am selling my current vehicle and she needs to cancel it and add new. I had to phone her back on Tuesday (after leaving 4 messages) I eventually got hold of her and she activated the policy on the new vehicle so I could get the proof for the dealership. SHE DID NOT CANCEL THE POLICY ON THE OLD CAR!!!! And this month the instalment went of as if I still have the car!!!!! the car was left at the dealership on Tuesday 27 March as I told her and now I am paying for a car I don't have?!?!?!? AND to top it all off, when we had our (very long) conversation she still asked me to leave a review on this site? Really!! Miway advertise their log-in service where you can change your policy etc. etc. etc BUT to get this thing to work is another pain I don't have time for! this app does not recognize my ID no!!!!
