Panera Bread review: Product and service

Dear Sir/Madam,
There are times when we ignore things, let things go or step up. This is a step-up take action time. I have had several incorrectly filled orders at the restaurant and have let most go and returned to have two orders redone {corrected}. On the first returned item I was told that they were out of the bread I wanted and used a substitute (did not advise me of this). I was given a refund. The second return tonight I was told the same thing. So, I asked if I could be told this at point of sale and I not fine out after arriving home and having to coming back. So, I changed to a bread that was available. Now I will say that my order was quite difficult as a wanted a plain tuna sandwich - nothing on it, just bread and tuna. I get to the window a young lady says "You get the tuna sandwich, right? YES! She picks up the bag go to the back for 3 or 4 minutes and comes back and says"I can't find the ticket for this, just take it." (she did not take my 2nd order the fellow who did original order did). I inform her it is a redo for a plain tuna sandwich. I get home I have tuna but also tomatoes, lettuce onions, pickles, etc.). I know you think why can't she just take off what's not wanted. Tuna is not like a slice of meat. The more things you take off a tuna sandwich the more tuna you lose. Been there done that on more than one occasion. I say why can't I get what I ordered.
I am done. On a scale of 1 to 10, I would rate you at 1. As this is about the number of times my order has been correct out of 10 visits. So you can see this is not about 2 orders but basically 9 I said nothing about. I can only blame myself, as errors/mistakes can't be rectified until management is made aware. I am making you aware.
This not happening at the 5th Street shop but also the Barracks Road shop in Charlottesville, Va. So, we can assume it is company-wide.
It starts with one unhappy customer and never stops. Good Luck!
