No assisting whatoever in cancelling my policy WORSE you expect me to pay for the deactivation of the tracker , when you sold me lies

I took out insurance on the a Thursday (mind you I'm a repeat client) it was ridiculously expensive. i got a cheaper insurance the following day. I called them imm to cancel and also sent email and follow up emails. After all that they sent tracker to be installed (confusion was dealer also sent someone I thought it was from the dealership) called dotsure again they told me need to +-2k for tracket to be deactivated, how cause I cancelled but you still sent some1 & I told the guy who sold me insuirance I dont ned tracker as I took one with the finance he said I must not worry its for free, todate DOTSUre has been quiet, none is responding to my emils its been week no help whatsoever. I AM VERY DISSPOINTED ESP AS A REPEAT CLIENT YOU SELL INSURANCE WITH LIES JUST TO GET A SALE OR HIGHER COMM MAYBE THE GUY THAT SOLD ME INS WAS A **** NOW CLIENT SERVICE WANTS TO PIN THE +-K ON ME HOW WHEN I SAID ON THE PHONE NO NEED FOR TRACKER. WHY IS DOTSURE QUIET &NOT RESOLVING MY QUERY, IS THIS HOW CLIENTS ARE TREATED??? CAN YOU COME TAKE THIS TRACKER OUT OF MY CAR &DEACTIVCATE IT. I AM NOT PAYING A CENT
