Alexander Reed Cleaners

I took seven items to this cleaners to be cleaned. One of the items was a dress and when I picked it up, they told me they were charging $10. They charged me for two pieces instead of one. It was a one piece dress and I should have been charged $4.50. She said because it's a long dress. She said they would have to charge $10. I didn't see any signs that confirms that. I didn't pay for it and I left. I went back and asked her for the prices written out. I told her that the other clerk told me everything was $4.50.
Then she said it is now $5.00. The dress is still there. They should put their prices up for consumers to know. There are no prices showing and they can charge consumers anything.
