BAD SERVICE

I went o Brooklynn Store on the 8th of Jan and order some stuff. They did inform me I will receive it in Feb, so in Feb when I phone they said no they still wait for the carpet it will be delivered in March. March I did phone them again now it will be delivered in April, but she will contact me. Since today I did not receive any email or phone call from them. How can you wait almost 3 months for stuff without informing your client
