Albertsons

I have had one problem with the store that keeps repeating, always out of at least one item I need for my recipe at the time. Sometimes it's uncommon item that I have to go to Vons for or what usually is is a very common item like split green peas that they can't seem to keep in stock. I have discussed this with employees over the past year. But their is nothing they can do about it. About 4 weeks ago when yet again this store fell short of an item I needed I talked to the General manager which is no easy task and time consuming. He apologized and yet again I ended up at Vons.
Yesterday I went in to redeem my stamps for a pan, I was told they ran out of every item and that they will have more tomorrow (today). I went back today I asked a cashier about redeeming my stamps she said I had to go to customer service. I went to customer service and there was a sign that stated see the cashier. Well to make a long story a little shorter. I was told to come back tomorrow that they still did not have the items. At this point I was not very happy and asked to speak to the general manager. 15 minutes later someone other then the general manager shows up. I went from being unhappy to being upset. Since I could not speak to the general manager I asked for the name and telephone number to the district manager, she gave me the name and number. I went home and called the district manager. Well wouldn't you know it, it was the wrong number. I then attempted to contact Albertson's Corporate office and was given a number to customer service. I find out that Albertson doesn't even do their own customer service they send it out to a third party. Now I am no longer unhappy or upset, I am pissed and only thinking at this point that Albertson's just has no respect for their customers at all. Going from store manager to Corporate office.
Now I am thinking of legal ways I can make Albertson's feel the sting of their anti-customer policies.
Anyone have any suggestions, I am willing to put in as much time and energy as it takes to get Albertson's to change their customer service policies to be customer friendly.
