Extremely dissatisfied customer!!!

I purchased a wall unit from Bradlows a couple of months ago and paid for it in full. It broke down shortly there after. I called Bradlows several times to have it sorted out, they took forever to come to my house. When they finally did, they saw that it was beyond repair and had to be replaced with a new one under warranty. They took it back with them and I was told a new wall unit would be delivered to my house with a few days. A month later I still had not received my new wall unit, I called them to enquire what the hold up was and I was told they were out of stock. When I asked when the new stock would arrive, the lady told me she doesn’t know. I waited another month and called again last week Friday to enquire again about my fully paid up wall unit and I was told by a constant at head office that my complaint was heard and someone would call me back within 48 hours I still haven’t received any form if communication for Bradlows Headoffice even after they promised to sort this mess out, not even so much as a phone call even after they promised to do so. I have never in my life received such pathetic service. What’s even more frustrating is that I paid a fortune and a half for such ****py furniture. I took my business to Bradlows thinking I would get good quality products and excellent service but I got the exact opposite. Its been 2months now and I still haven’t received my new wall unit even after they took back the faulty one.
