SOLD ME WRONG VEHICLE PLAN

Good day December lat year i got an sms stating that my service plan was going to expire, i called sa warranties and spoke to zama khumalo who assured me that it would be renewed and it would be an even better one which would cost R350.00 so i gladly agreed to take it, then earlier this year around march i took my car to bosch in alberton the service was done it was paid for, then on the 25/05/2015 i took my car to bosch for my 210000km service they called ans said it could not be service as i have a maintainance plan, when i spoke to zama she assured me that my car would be serviced,so i called sa warray spoke to ingrid who was not friendly and gave me bad attitude i got upset and cancelled the policy immediately, should i not be reimbursed for being sold the wrong product also i asked for the recording of me speaking to zama it hasnt been sent, this company has really let me down and hurt me very bad.
