Very angry

You know am very angry with this company BUDGET INSURANCE I had car insurance with them and they requested thee tracker be fitted in the car I did put the tracker in the car and they came back and said the tracker that I have installed is not the one they prefer I should upgrade because hijack and theft will not be covered so then I decided to cancel my insurance so on Friday I called and spoke to a very arrogant ,*********** guy who said he name is Shezi ,am not sure if he gave me the correct name or not , very unprofessional guy ,he did not want to listen to anything ,he argued with anything I tell him and I clearly stated that I want to cancel my insurance he kept arguing and a the end he said I canceled your insurance but only to find out that he posted the cancelation for 31 August ,so he decided on my behalf that the insurance is going to be canceled on 31 August ,so now yesterday budget insurance deducted the premium so when I ask why they said I still have insurance with them ,and I said no I canceled on Friday but only to find out that the guy who was helping me choose 31 August and now I have to pay 2 insurances because of this arrogant guy who chose a date for me and they don't even want to refund me my money ,I am very angry and disappointed at this company and am asking myself why would I still want to continue with this company because they said they won't cover theft and hijack ,but Shezi decided that I should continue with them until August ,very disappointing ,service of that insurance has been nothing but a headache to me.
