Unhappy client

We ordered a couch in December 2020, the delivery was on time but wrong. We ordered a light grey couch to fit with my curtains and style but the dark grey was delivered, we didn’t choose the light grey as we didn’t like the material. When we ordered we sat on the light grey and told the sales lady we wanted that exact one. We didn’t se she made a mistake on the invoice and upon delivery they delivered the dark grey one. Now the material is faulty and the stitches is going loose. Its expensive couch for the wrong color to be ordered and for the stitches to come loose after not even a month. Customer care is not great!
