Long Delay and no follow ups

Key set ordered on Friday 31 July and was promised that car will be fixed the following week. I asked that the car be ready by Friday 07 as I need to travel on weekend. Ralph assured me that key set will arrive Tuesday or Wed latest, only when I called on Thursday to follow up I was informed key set arrived but car can only be fixed on Tuesday 11 Aug. I'm inconvenienced and frustrated by the poor service from Nissan The Glen, the entire week I followed up myself and the attitude from the staff is very poor with no customer service. I would not recommend this Nissan to anybody as there is not customer service and I am told that I am not the only customer, there is total disregard to clients. I would prefer a written apology and a call from the dealer principal in this matter. The whole week i also mentioned that I have to travel on Friday and now i am inconvenianced at last minute.
