Utterly disgusted, worst service I have ever experienced

I gave my curtains in for dry cleaning, and got them back in tatters. They were washed in a washing machine instead of being dry cleaned and no one is claiming responsibility. They then refused to give me the owner’s name and number. Instead, the manager told me it’s because the curtains are old! This is the worst service I have ever experienced and the damage done to the curtains is to the extent that I would have to replace them completely.
