FORD SERVICE REPAIR MESSUP

I booked my vehicle for a service on 22.09.2022, I was told i would need to replace the brake soon and there seem to be rats in the engine area however no damage has been cause. on 23.09.2022 the malfunction light( Engine check) illuminated and i had to drive all the way from EC only to get there and be told by the consultant that the rats caused damage, i then requested to be shown the damage and even before the technician advised which wires were damaged the consultant gave me a quotation from the top of her head of R2200.00, suddenly the consultant spoke to the technician on the phone in afrikaans and i was not shown any damage and the technician came back with the car and told me there was a fuse that burnt and he managed to fix it. i checked the car and the light went off i drove off for about +- 3 minutes and it went on again. i took the car back and the technician advised that the car needs to be diagnosed....... I am puzzled as to how is it the car is being checked after it has been serviced and no faults were seen on the car.... they clearly did not do any service repair on the car and i am just being taken for a ride and expected to pay more money. i since left the car there on 26.09.2022 till now i have not received any call about the status of the car. Park ford does not take me seriously.
