Car faults on ford fiesta 2012

[FordFocus2016]

Hi guys/girls I have an issue and would like some help basically  a garage has had my car for 7 weeks five days the problem with the car was fuel injector 1 needed replaced 3 need to be refurbished  fuel pump injector near engine needed replacing and also a faulty wire in the car my point is can it take over 5 weeks to find a wire fault on a car I personally think it rather excessive.   

Thanks
