Unhappy customer

Last week I bought a dress at Superbalist and a wrong colour was delivered. I sent an email expressing my dissatisfaction and I don’t feel my concern was taken seriously. I then today I decided to buy a T-shirt and paid for the same day delivery since it was an option. I never received my parcel and no explanation whatsoever. I am starting to think Superbalist is not caring for the customer’s support anymore or things like these would not be happening often.
