Part not in stock after asking for confirmation several times.

I had a faulty sensor on my Ford and after having to phone them three times to get the correct part and price, they finally were able to assist me. This was a Friday afternoon and I asked the several times if they have the part in stock as I will drive through the next morning to avoid traffic. The confirmed 100% that they have the part in stock so I drove through the next morning to collect the part and guess what........THE PART WAS NOT IN STOCK! This cost me a lot of time and petrol to drive through and their response was "Sorry, we can order you another one" The fact that they could care less about the discomfort this cause me and I have to come back again to collect the part, was shocking. We all know customer service in the country is extremely bad and we must just accept it is so sad. I would urge this branch manager to instill more pride about there work into his team, they seem to be there just for a paycheck at the end of every month. Very very disappointing experience..
