Cheated by Housefull furniture and customer care is not responding

Location/place: Navi Mumbai

Name of company/service: Housefull Furnitures

We booked two home furniture units from Housefull Vashi store on 3rd March 2013. HDC No. is 1009/2013/652. The products are:
1. Brooklyn Shoe Rack MH7003. Product Code: 100006418 We paid Rs.5450.00 for the product.
In the store the actual price of the product mentioned was Rs 12,380 and after 56 per cent discount it was Rs 5,450.
After getting delivery of the product, we found that the printed price on the product is Rs 5,000 (inclusive of all taxes).

We were over-billed for the product and INSTEAD OF SAVING 56% ON THE PRODUCT, WE WERE BILLED @110%.

2.The second product was Sedron TV Cabinet MH 8051 Product code: 100008514
Same issue with this product. Price mentioned was Rs 22,000 and post discount the cost is Rs 12,350 (44 per cent discount). But the actual price of the product mentioned on the packing was Rs.15,000.

I have called n number of times and sent many mails. But I am not getting any satisfactory response.

Nobody is ready to answer that why they have charged more than the print price.

The quality of the product is also not good. Doors started bending after 5/6 days of use.
They are not sending the carpenter after lodging the complaint.
