Special Occasions very slow in returning deposits

Lovely dresses, assistance is excellent but that's about where it stops. I hired a dress for my daughters wedding. I was promised that alterations would be made as requested. On the Friday morning of collection, the alterations were not made as promised as the owner said no alterations were allowed. I then requested my money back. Then al of a sudden the alteration could be made. The dress was returned in a good condition the Monday morning and was informed that it takes 2 weeks to return the deposit. It has now been two weeks and no deposit has been returned. No reply to my email and no response to whatsapp. Be aware of the admin implication when hiring a dress from Special Occasions.
