Bad customer service

I'm sooo not impressed with the service i got today. So i called today and was assisted by a guy named Tshidiso, i know that my contract with Cartrack have matured so i can cancel free of charge, yet this woman was forcing that he has to send me a form that i must fill and send back, i kept on telling him i already spoke to someone they said i can cancel free of charge over the phone, after arguing with this guy for a good 10min he put me on hold then said oh ok mam i can help you cancel like....??. Yoh hai now i dont even regret cancelling shame ke sharp.
