Still waiting

My mother made contact with Andre about 2 months ago informing him that the foam of her contessa lounge suite which I bought her from the branch is no longer stiff, they collected the furniture back then but now we still awaiting for them to return it, how is it possible to replace inner cushions for about 2 months, my mom's guest has to sit on plastic chairs, my mom constantly calls them to enquire how far they are and then my mom gets excuses or the run around, this is totally unacceptable, I'm demanding that those cushions be replaced and that my mom gets her furniture by friday or i will take further steps.
