Bad Service, No Feedback, Useless Sales personel

On the 22/01/2016 I ordered blinds from Builders Warehouse and I was informed that I will be contacted when the blinds would be available. After weeks I called in for an update but I was put through to the department and I was holding on the line and no one answered.Today 24/03/2016 I decided to go back to the store to see if my blinds have been delivered, to find out that the blinds were delivered on the 03/03/2016 to my surprise no one had bothered to call me to inform me. I have been waiting for the whole month and if I hadn't gone back to the store I wouldn't have been informed. Your service is pathetic and appalling. Your sales department is useless and know nothing about customer service. How can you have a customer's good laying there for a month without following up. Your staff claim they called me and left a voice message but I didn't get any missed call or voice mail message. Your sales staff are not only useless and unhelpful but they are ***** as well.
