Russells Furniture, terrible communication and service

I am so dissappointed with Russells Furniture, I did a laybye and when I went to pay off my credit I was informed the lounge suit I wanted was sold and discontinued, and this I wasnt informed before placing my laybye, I didnt want anything else so I asked for a refund, and I was asked to bring in a few documentation papers for this, I didnt have an issue, the issue I have is I submitted my documents the weekend of the 17th of March and to date I havent received my refund of 6000 and when I ask for escalation to finance I am told they dont have the Finance departments number????????????????????????????? what company does that at a national level
