Pathetic and ***** service

this company just know how to reap off people, i bought a new car and requested for a quote i was qouted R119 and was paying the similar amount for the previous car, so i have another car with them already and the sales person told me i will iony R119 monthly and agreed to take the contract and she also requested for me to upgrade the existing one but to my suprise my invoice was over R700 for both the cars , when i call to make enquiries i am told that i am still pay for previous contract, what i don't understand is the ridiculous amount they are charging me and the lies they told me and why i am paying for two contracts for one car. and why i was told i will pay R119 for each car and now im paying around R700, i should have opted fr cartrack R99 instead and they bind you to their stupid contract knowing exactly they wll do this to you, i'm so angry.
