Best Cleaners - gown preservation

I used Best Cleaners to Clean my dress prior to my wedding as I purchased my dress off the rack at David's Bridal. I also used their seamstress to put the bustle in my dress, fixing some beading, and taking the buttons in an inch or so. I left my dress there and was told someone would call me to let me know how much it would cost to clean the dress since it depends on the dress material. No one EVER called me to tell me the price. I got a call saying that it was cleaned and that I should come in to begin the alterations. So I went to have her pin it for the alterations, but when i put it on in the dressing room, it got dirty again from their filthy floors. I pointed this out and was promised it would be cleaned. The seamstress was very nice and did a great job fixing the beads and taking the buttons in as I had lost a bit of weight since purchasing the dress. I was not so impressed with the bustle however since there were hooks that came undone several times throughout the night and part of my dress dragging in the back. Which of course led to me stepping on it and made for some not so great photos. Now for the cleaning. I had them keep the dress until a week prior to the wedding so that it would be freshly pressed. When I picked it up and brought it home, there was a BLACK spot on the front of my dress that was not there prior to them cleaning it. Not to mention that the bag (newly purchased from David's Bridal) was Filthy at the bottom with two quarter size holes in it. I called and was told to bring it in the next day which I couldn't since I had to work and live 45 minutes away. I ended up calling the first morning I was able to bring it in and was told to bring it to the Latham store and it could be taken care of that day. So I brought it to the Latham store and they had NO IDEA what I was talking about. I spoke with the "wedding dress" person on the phone and she promised me that if I left it there over night she would have it back to me the next day, clean and pressed. So I left it there and came back the next day to pick it up, this time checking it over VERY carefully and the black spot was gone, but another smaller black spot appeared on the back. I was again put on the phone with a manager who promised me I would get 30% back from the cleaning I originally paid for. It has been over a month and they have giving me nothing back. I WOULD NOT HAVE MY DRESS CLEANED HERE OR PRESERVED. Once it's preserved in a box, you'll never know how many black spots there are until you take it out many years later!
