Order stock, paid for, but absolutely no service!

Went into Nissan Hatfield, ordered a part and had to pay for it. I was told that I will get it the next day. Next day, I go in to pick up the part, but when I got there, I was told that the part was not yet delivered, but that I will be phoned later that afternoon to get feedback as it shows that there is one in stock but they can't find it. Got no phone call. Left it for a week in the hope that should I go there again, the part will be there. Went there again after a week, and again was told that it has not been delivered yet. I asked why Leroy has not phoned the warehouse, but was told that he cannot phone, but only email and he has not received any feedback as yet. I feel that is absolutely nonsense! And then when he looked on the system, it said 3 months to deliver - a typing mistake that could cause me to wait a very long time! Leroy is not concerned about service delivery at all! If this is how Nissan Hatfield treat their consumers, I will definitely not use or recommend them ever again!
