very bad after sales service

Your team (https://appliancesrepaircapetown.co.za/) came to fix my dishwasher. Before they started I requested a report of the fault with the dishwasher which they did not give me and it is needed for the insurance. Now the man that answers the phone on 071 997 4659 said I must pay R450 for the report. I find this to be very excessive. Also the sensor was not replaced as it says on the invoice.
