Bad Customer Service

I personally went in to book my car for a service and key programming for thw 21st November. They keep my car the whole day on 21st when I fetch I discover that only the key was done they only booked for one thing instead of two like I said. they then promised me that they will fetch my car on the 23rd , they had asked for the 24th I told they I cant afford to be without a car on the 24th unless they will give a car. When then said 23rd as they said they don't have a car to give me. on the 23rd no one came or called. Received a call around 11 am on the 24th asking me if they can fetch my car. I tell them , that they we meant to fetch yesterday and I had said I needed a car on this day. She then promised to fetch the car on the 28th. 28th no one called or came so around 12 pm I call to inquire no one knows anything about my car. I was transferred to the Manager who told me the service lady is sick . I tell him I m traveling over the weekend hence I needed the car to be service he tells me it should be safe to travel without seeing my car or asking my car registrations to check my service history on his system. on the 29th I receive a sms message from the service lady telling me she was off sick and doesn't know why my car wasn't fetched. She asked to reschedule I tell her the only day I can stay without a car is now next Wednesday .She books it for Next Wednesday . I report this on their facebook page no one contacts me. As I valuable customer I should not be treated this way. Still waiting for much more to be done with this matter.
