Poor Service seems to be consistent

I took my vehicle for an annual service today. I received absolutely poor service. I feel that I was not treated fairly. After dropping the vehicle off at around 7:30am I received a call around 11am to advise that my wiper blades need to be replaced, which I immediately advised that I have a maintenance plan , the service advisor ask me to sms or email proof(last year they did my brake pads so I didn't feel the need) however I sent this 30minutes later. I had to follow up via email as my calls were not getting attended to nor returned. The 2 main issues were from 3:15pm I tried calling my service advisor and left messages and emails to return my call as nobody has called to advise if the vehicle is ready(not even a call to say all went well). at 3:55pm I get a call from the driver to say he is 2minutes away, really poor communication, I mean no one called to even tell me my car is ready and the driver is on the way??? further to this after requesting my service book to be stamped, I now find an unstamped book??? I told the advisor at 7:30am to ensure this gets done(not that I should be telling how to do your jobs) I need my book stamped, This is a huge Impact as I am looking to sell this vehicle and a potential buyer has requested this information. I have not been treated fairly from the beginning. I have a BMW as well and your neighbours treat me with world class service, which you guys should aim for. they call you to advise you from start to finish . I really hope this is not your standard service level as I have had the same experience last year January and waited outside 20minutes for the driver in the afternoon, lets not go there but the poor service seems to be consistent. I don't know whether to purchase another Ford due to this or just use another branch to service my next potential vehicle
